Does the old specgram() function pertain to the Short Time Fourier Transform or at least related to it? The function was used as [B,F] = specgram(s,n,FS) in a sample program I got. What do the results B & F mean?
EDIT: Additional Question: How do I know the number of n or nfft needed? I used the length of the input signal as the n.
