peak fitting

各种算法可以用来进行曲线拟合. % 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
