I want to measure the similarity of two time frequency diagrams;each time frequency has three outputs:
S (spectrum in form time x frequency x channels/trials if trialave=0; in the form time x frequency if trialave=1)
t (times)
f (frequencies)
Is there a predifined funcyion in atlab or i need to divide values of each by the other values?

xcorr can be used to find cross-correlation of two discrete time sequences. I think you can use that in funding similarities between two frequencies at different time stamps. Here is the link for that xcorr, please refer that for more information:
Hope this helps!
