% A command-line peak fitting program for time-series signals, written as a self-contained
% Matlab 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 wpeakhether 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. Fits any number of peaks of Gaussian, Lorentzian,
% equal-width Gaussian and Lorentzian, fixed-width Gaussian and Lorentzian,
% biburfated Gaussian and Lorentzian, exponentially-broadened Gaussian,
% Pearson, Logistic, exponential pulse, sigmoid, Gaussian/Lorentzian blend,
% and Voigt shapes. This is a command line version, usable from a remote
% terminal. It is capable of making multiple trial fits with sightly
