Curve Fitting Toolbox

Fit curves and surfaces to data using regression, interpolation, and smoothing
  • Linear and Nonlinear Regression
    Fit curves or surfaces with linear and nonlinear library models and custom models

  • Interpolation
    Fit interpolating curves or surfaces, estimate values between known data points

  • Smoothing
    Fit using smoothing splines and localized regression, smooth data with moving average and other filters

  • Fit Postprocessing
    Plotting, outliers, residuals, confidence intervals, validation data, integrals and derivatives, generate MATLAB® code

  • Splines
    Construct splines with or without data; ppform, B-form, tensor-product, rational, and stform thin-plate splines
