MATLAB: Please explainn this and guide me to develope the code

digital signal processingsignal processingSignal Processing Toolbox

[P,F] = spectrum(SSSS,128,0,hanning(128),1/15);
is the old version of matlabs solution to find the spectrum of the signal named 'SSSS'.
can any one explain this ??
what is the equivalent of above spectrum, that compatible to the latest version of MATLAB ?

Best Answer

You can do the following
      [Pxx,F] = pwelch(SSSS,hanning(128),0,128,1/15);
The syntax you are using above is:
   [P,F] = SPECTRUM(X,NFFT,NOVERLAP,WINDOW,Fs)
to get the equivalent in an updated version of MATLAB use the corresponding syntax for pwelch.m
