The present submission deals with the simulation of turbulent wind field (u,v,w, components) in 3-D (two dimensions for space and one for the time). The computational efficiency of the simulation relies on Ref. [1], which leads to a significantly shorter simulation time than the function windSim, also available on fileExchange. However, only the case of a regular 2D vertical grid normal to the flow is here considered.The submission contains:- An example file Example1 that illustrates simply how the output variables look like.- An example file Example2, which is more complete, and which simulates a 3-D turbulent wind field on a 7x7 grid.- An example file Example3, which illustrates the implementation of the quad-coherence to generate a turbulent wind field.- A data file exampleData.mat used in Example1.- The function windSimFast.m, which is used to generate the turbulent wind field. A similar implementation of windSimFast.m was used in ref. [2].- The function getSamplingpara.m, which computes the time and frequency vectors.- The function KaimalModel.m, which generates the one-point auto and cross-spectral densities of the velocity fluctuations, following the Kaimal model [3]. I have corrected the cross-spectrum density formula used by Kaimal et al. so that the simulated friction velocity is equal to the target one. - The function coherence used to estimate the root-mean-square coherence, the co-coherence and the quad-coherence.References: [1] Shinozuka, M., & Deodatis, G.

For a more robust and time-efficient Matlab implementation, see https://se.mathworks.com/matlabcentral/fileexchange/68632-wind-field-simulation-the-fast-version.SummaryA method to simulate spatially correlated turbulent wind histories is implemented following [1,2]. Two possible vertical wind profiles and two possible wind spectra are implemented. The user is free to implement new ones. The wind co-coherence is a simple exponential decay as done by Davenport [3]. If the wind field is simulated in a grid, the function windSim.m should be used (cf. Examples 1 and 2). For a more complex geometry, such as a radial grid, the function windSim.m has an optional parameter to include two inputs (cf. Example3.mlx): The first one contains the wind properties, and the second one contains the coordinates of the nodes where wind histories are simulated (cf. Example 3).ContentThe submission contains: - 1 input file INPUT.txt for Example1.m - 1 input file INPUT_MAST.txt for Example2.m - 2 input files windData.txt and circle.txt for Example3.m - The function windSim.m- The function getSamplingPara.m which get the time and frequency vectors - 3 examples files Example1.m, Example2.m, Example3.m - The function coherence.m that computes the co-coherence. Notes: - Simulating the wind field in a high number of points with a high sampling frequency may take a lot of time. - This code aims to be highly customizable A more straightforward version of the present submission has been used to simulate the turbulent wind load on a floating suspension bridge [4].References[1] Shinozuka, M., Monte Carlo solution of structural dynamics, Computers and Structures, Vol. 2, 1972, pp. 855 – 874[2] Deodatis, G., Simulation of ergodic multivariate stochastic processes, Journal of Engineering Mechanics, ASCE, Vol. 122 No. 8, 1996, pp. 778 – 787.[3] Davenport, A.

The Time domain decomposition (TDD) [1] is an output-only method to extract mode shapes of a structure. Here, the modal damping ratios and modal displacements are in addition extracted using the functions presented in [6]. The TDD is similar to a more popular technique called Frequency-domain method (FDD) that was introduced by [2,3]. A good example of the FDD already exists on the Matlab File Exchange [4]. In a previous version, the present submission contained a function for the FDD. This function has been modified and moved to a new submission [5].This script contains:- The function TDD.m: function to apply the TDD method.- An example file Example1.m- Acceleration data beamData.m (4 Mb) Comments, suggestions for improvements and questions are welcome.

The estimation of the displacement response of a large civil engineering structure to wind turbulence is based on the buffeting theory [1, 2, 5]. Ref. [5] contains the theoretical background I have used for the function dynaRespFD3. In the present script, the structure in question is a suspension bridge modelled using the theory of continuous beams [3]. The buffeting response is computed in the frequency domain using the quasi-steady theory. Modal coupling was assumed negligible, which is generally well verified for most of the wind velocities recorded in full scale [4]. The present script is a simplified version of the one used in [6]. The present script computes the lateral, vertical and torsional displacement response. A multi-modes approach is used. Some knowledge in the field of random vibration analysis and wind loading on structures are advised for proper use of this script. The present submission contains • dynaRespFD.m : Function that calculates the displacement response spectrum of the bridge• A function VonKarmanSpectrum.m to generate the power spectral density of the velocity fluctuations based on von Karman model.• Two example files Example_1.m and Example_2.m• Two .mat files bridgeModalProperties.mat and DynamicDispl.mat that are used in the 2 examples.Any question, comment or suggestion to improve the submission is welcomed.References [1] Davenport, A.G., The response of slender line-like structures to a gusty wind, Proceedings of the Institution of Civil Engineers, Vol. 23, 1962, pp. 389 – 408.

regularizeNd Fits a nD lookup table with smoothness to scattered data. Constraints are possible. regularizeNd answers the question what is the best possible lookup table that the scattered data input x and output y in the least squares sense with smoothing? regularizeNd is meant to calculate a smooth lookup table given n-D scattered data. regularizeNd supports extrapolation from a scattered data set. The calculated lookup table, yGrid, is meant to be used with griddedInterpolant class with the conservative memory form. Call griddedInterpolant like xGrid = cell array of grid vectors smoothness = smoothness value or vector yGrid = regularizeNd(xData, yData, xGrid, smoothness); F = griddedInterpolant(xGrid, yGrid). Desirable properties of regularizeNd: -Calculates a relationship between the input x and the output y without definition of the functional form of x to y. -Often the fit is superior to polynomial type fitting without the wiggles. -Extrapolation is possible from a scattered data set. -After creating the lookup table yGrid and using it with griddedInterpolant, as the query point moves away from the scattered data, the relationship between the input x and output y becomes more linear because of the smoothness equations and no nearby fidelity equations. The linear relationship is a good choice when the relationship between x and y is unknown in extrapolation. -regularizeNd can handle 1D, 2D, nD input data to 1D output data. RegularizeData3D and gridfit can only handle 2D input and 1D out (total 3D). -regularizeNd can handle setting the smoothness to 0 in any/some axis/dimension. This means no smoothing is applied in a particular axis/dimension and the data is just a least squares fit of a lookup table in that axis/dimension. Note this is not recommended and often can lead to an ill-conditioned fitting problem. However, I have found it useful so I left this as an option. - Constraints are possible with the function regularizeNdMatrices. See the example.The source code is locate here: https://github.com/jasonnicholson/regularizeNdFor an introduction on how regularization of a lookup table works, start here: https://mathformeremortals.wordpress.com/2013/01/29/introduction-to-regularizing-with-2d-data-part-1-of-3/Acknowledgement Special thanks to Peter Goldstein, author of RegularizeData3D, for his coaching and help through writing regularizeNd.

This submission contains functions implementing the fractional linear prediction (FLP) models to estimate the one-dimensional signal. Two versions of FLP are implemented. The first approach to FLP is using the whole history of the signal ("full" memory) - function flp_f.m. The second approach to FLP uses the "restricted" memory (restricted to two, three or four previous samples) - function flp_r.m. The methods, models and applications implemented in the form of the proposed functions were presented in the works [1], [2]. The MATLAB implementation of the discretization of the fractional order derivative can be found in [3]. [1] Tomas Skovranek, Vladimir Despotovic: Signal prediction using fractional derivative models.

Click on the Examples Tab ^^^ for detailed descriptions of AMT functions. This toolbox is for importing, analyzing, and displaying Antarctica-related data. AMT is designed to provide a standard framework to allow easy pairing of multiple different types of data sets (surface elevation, ice velocity, grounding line, etc). For a quick overview, check the Examples tab on this page and click "AMT Getting Started". To find data-specific plugins for this toolbox, search the File Exchange site for "AMT".Note to users: AMT was originally written to be used with Matlab's Mapping Toolbox. However, Matlab's Mapping Toolbox is sometimes inefficient and difficult to work with. And depending on Matlab's Mapping Toolbox makes it harder to share codes. So I've been moving more toward plotting mostly in polar stereographic meters. There is a suite of functions ending in "ps" that make this easy. If AMT is useful for you, please cite our paper!

Voltage and frequency grid codes, such as IEEE 1547-2018, dictate how distributed generation, such as utility-scale solar and wind, must remain connected during grid fault events. These examples show how you can evaluate grid code compliance in MATLAB against historical measured data from PMUs. Additionally, Simulink blocks provide a path to evaluate grid code compliance of simulated systems and protection logic.For more information and a video walk-through, these examples are used in the "Renewable Grid Integration Studies with Simscape Electrical" Webinar to evaluate grid code compliance of renewable and distributed resources: https://www.mathworks.com/videos/renewable-grid-integration-studies-with-simscape-electrical-1543529438031.html

The position of the sun is an afterthought for most, unless it is blinding you on your commute home. However, the position of the sun remains incredibly important, even in the modern age. While solar navigation through sextants was common until GPS came along, architects/engineers still track the sun for building shading and solar panel optimization. This script dives into the "analemma" which is an interesting phenomenon associated with solar observations. Try testing different latitudes to see how the sun's trajectory changes and what the analemma looks like!

## SummaryThe function SSICOV.m aims to automatically identify the eigenfrequencies, mode shapes and damping ratios of a line-like structure using ambient vibrations only. The covariance-driven stochastic subspace identification method (SSI-COV) is used in combination with a clustering algorithm to automatically analyse the stabilization diagrams. The algorithm is inspired by the one used by Magalhaes et al. [1]. It has been applied for ambient vibration monitoring of the Lysefjord Bridge [2] and was compared to the frequency domain decomposition technique [3]. Finally, the algorithm was found accurate enough to visualise the evolution of the bridge eigenfrequencies with the temperature [4].## contentThe submission file contains:- A data file BridgeData.mat- A Matlab Live Script Example1.mlx that illustrates the application of the algorithm.- A Matlab Live Script Example1_noToolbox.mlx that reproduce Example1 but using the function SSICOV_noToolbox.- The function SSICOV which is the automated SSI-COV algorithm.- The function SSICOV_noToolbox which is the automated SSI-COV algorithm but does not use the Statistics and Machine Learning Toolbox. The Linkage algorithm is replaced by the function "PHA_Clustering" by [5] and the function "cluster" is replaced by the function "Cluster2", which is derived from [6].- The function plotStabDiag.m, which plot the stabilization diagram.Any question, suggestion or comment is welcomed.## References[1] Magalhaes, F., Cunha, A., & Caetano, E.

What´s the minimum distance between two SuperEllipsoids? What's the maximum overlap between two SuperEllipsoids?A proximity query contact detection between convex superellipsoids surfaces using its implicit equations.The contact detection of two superellipsoids is formulated as a convex nonlinear constrained optimization problem that is solved using fmincon function, with an Interior Point method. The objective function to be minimized is the distance between both surfaces. The design constraints are the implicit superquadrics surfaces equations and operations between its normal vectors and the distance itself (several constraint sets can be selected). The contact points or the points that minimize the distance between the surfaces are the design variables.The visualization of the surfaces, the initial estimate and the optimization solution for the minimum distance is provided.References:- Portal, Ricardo.

* * * The functions on this page are no longer being updated. They should still work as shown in the examples here, but I am only actively maintaining the versions of these functions which are in the Climate Data Toolbox for MATLAB, which can be found here https://www.mathworks.com/matlabcentral/fileexchange/70338. * * *This submission contains functions to plot the outlines and names of National borders and US states. Matlab's Mapping Toolbox is NOT required. There are two functions for plotting: borders and bordersm, and they both work the same way, except that bordersm is for use with maps created using Matlab's Mapping Toolbox. Similarly, labelborders and labelbordersm place text labels within the boundaries of countries or states.

Modeling operations often perturb a model's layout. Layout readjustment is usually needed, and represents a tedious activity if performed manually. Although achieving a proper layout of a Simulink model is deemed very important, there does not exist a comprehensive commercial automatic layout tool for Simulink models. The Auto Layout Tool resizes models' blocks based on number of inputs and outputs, and organizes the signal lines such that the number of crossings is minimized. Auto Layout Tool can leverage three different layout approaches: 1) "Graphviz", a third-party open source tool for drawing graphs; 2) Matlab’s built-in "GraphPlot" layout capability; 3) an in-house "DepthBased" method. Approaches 1) and 3) can be utilized on any version of Matlab/Simulink, while approach 2) only works on R2015b+.• For installation instructions and instructions on how to use the tool, see Auto-Layout/doc/AutoLayout_UserGuide.pdf.• This tool relies on our Simulink Utility. Please download it here: https://github.com/McSCert/Simulink-Utility.For more about the capabilities of the tool and how it can be used in model-based development with Simulink, see the following two papers:[1] Vera Pantelic, Steven Postma, Mark Lawford, Alexandre Korobkine, Bennett Mackenzie, Jeff Ong, Marc Bender, "A Toolset for Simulink: Improving Software Engineering Practices in Development with Simulink," In Proceedings of 3rd International Conference on Model-Driven Engineering and Software Development (MODELSWARD 2015), SCITEPRESS, 2015, 50-61.

We can estimate the time of sunrise and sunset for any location on the earth if we know the latitude, and longitude for that location. To estimate sunrise and sunset for any day of the year we need to calculate two values for a given date and place -- the equation of time and the hour angle.This live script illustrates the technique used to estimate sunrise and sunset times.

One method to compute the friction velocity knowing the along-wind and vertical turbulence components relies on the ogive function. For turbulence modelling, it is useful to ensure that the simulation duration is long enough to reduce the random error and to include all turbulent ranges. The present submission implements a simple ogive function model based on the semi-empirical model proposed by Kaimal et al. [1]. In the example file, it is fitted in the least square sense to ogive function computed with simulated data. The output of the fitting is an estimate of the friction velocity. The submission contains:•The function ogiveFun.m that computes the ogive from the cospectral estimate.•The function fitOgive.m that fits the analytical ogive model to the one estimated with the function ogiveFun.m.•A data file data.m containing time series of u and w•An interactive example file Example.mlxAny question, suggestion of comment is welcomed.Reference(s):[1] Kaimal, J.
