Respected Sir, I am very thankful for your quick response, yes I am able to get the matrix, but I am having trouble in converting that matrix into frequency vs time,can you please elaborate, as you have knowledge of signal processing, how would I be able to convert the output matrix into frequency vs time
I want to plot frequency vs time from the sound data(i.e. column data). I am not able to do it. Please please help. the specgramdemo function when run give at what time what frequency is present, but i want that it should return mtrx frequency vs tim

If i use the spectrogram function, it plots the spectrogram i.e. it plots frequency vs time but, i am not able to extract that information in to matrix. Please help.

spectrogram returns matrices containing the complex-valued short-time Fourier transform and the short-time periodograms.
See the help for spectrogram for examples.
