Spline Postprocessing
Evaluate splines, plot, find minimum or zero-crossings, integrate or differentiate
After fitting a spline, use postprocessing methods to analyze if the fit to the data is accurate.
Use Curve Fitting Toolbox™ functions to perform tasks such as plotting, evaluating, or calculating derivatives, integrals, and differences between splines.
