MatEssentials

A folder containing essential MATLAB functions that are not included in the standard distribution.

MatEssentials

MatEssentials (from Matlab Essentials) is an attempt to fill the gaps of common programming functions that are not included into the base installation. Some of these functions are for example lerp, sigmoid, linespacen, rot2d, rotx, random, randint, depfun, isodd, isneg and many others. Additionally, we provide an extensive color packages with syntax color_ and colormaps under cmap_ (based on the matplotlib in Python).

Installation

We highly recommend installing the essentials package using the Matlab Package Manager (MPM), which can be easily installed via the Matlab Add-On Mananger . Once MPM is installed, the essential package can be installed by the following command in the Matlab command window

mpm install matessentials -u https://github.com/BJCaasenbrood/MatlabEssentials.git --all-paths

This will generate a folder under MATLAB Add-Ons/Collections/mpm/mobeets-mpm-c626429/mpm-packages/matessentials/.

Improved Matlab colors

The package comes with an improved color pallete for plotting. To set and fix the colororder, use set_colororder.

To revert back to the default matlab colors, use set_colororder(cpal_matlab);

Improved Matlab colormaps

Matlab lacks many of the standard colormaps. Colormaps in the package are based on the ones from Python in the package MatPlotLib, which are given under cmap_.... These colormaps can also be modified using an additional input, e.g., cmap_turbo(-1) flips the colors, whereas cmap_turbo(0) mirrors the colormap.
