25 Apr 2013 Short Time Fourier Transform Script for computing the short time Fourier transform of 1D signals. Author: Hafeez Dhalla Anton Semechko

This is a pretty sloppy implementation of short-time FT. There are no default settings provided and the function throws an error if you specify a column vector instead of a row vector as a your input signal.

where is the code? please

Additionally, zero padding should never be done prior to applying a windowing function to your data. This will distort your window function and the results. I believe the first FFT is incorrect.

I don't see where you are scaling the FFTs in your funciton. Each FFT should be scaled by L for complex or L/2 for real valued input.
