Short time fourier transform (stft) in matlab

The following Matlab project contains the source code and Matlab examples used for short time fourier transform (stft). %% function [t,frequency,Power_spectrum]=fft_s(y,windowlength) %% Inputs : % y: input raw signal % windowlength: window length to take fast fourier transform, it is a % factor of smapling frequency for example one can enter a window length % half of the sampling frequency by enteríng 0.
