An interactive peak fitting program for time-series signals, written as a self-contained function in a single m-file. Uses a non-linear optimization algorithm to decompose a complex, overlapping-peak signal into its component parts. The objective is to determine whether your signal can be represented as the sum of fundamental underlying peaks shapes. Accepts signals of any length, including those with non-integer and non-uniform x-values. See http://www.wam.umd.edu/~toh/spectrum/InteractivePeakFitter.htm for more information. Version 13.2, December 2018: D key saves model to disc as SavedModel.mat, containing two matrices: DataSegment and ModelMatrix. To place model in the workspace, type load SavedModel; to plot saved DataSegment, type plot(DataSegment(:,1), DataSegment(:,2)); to plot SavedModel, type plot(ModelX,ModelMatrix); each component in the model will be plotted in a different color.
