In your posted code, fs would be the sampling frequency. The sampled values would be in y. You would proceed to fft(y) and then analyze the results along the lines I mentioned.
Note: your y might have multiple channels, which will show up as separate columns. Be careful, as in theory the different channels can have different peak frequencies.

% you will not convert (262144 is 4 times 256*256 and not equal to it)
% but complete 4 matrices out of your "aa" vector
% and you will get a "M" array:
M=nan(256,256,4); % pre-allocate
for i=1:4
