I have a window frame B and B is an array of 1x(length(frame)). I have a signal that is divided into 10 segments that is as long as length(frame) with 50% overlap 'hop' that is hop = length(frame)/2. The segment is saved in an array 'Fil' of size length(frame) x 19. I want to take the fft of every segment with a window applied to it.It is all done in a for loop with k = 20 and FFT is a newly created array in the loop. I used this line of code but it give me the error in the title.
for n = 1:k -1
FFT(:,n) = fft(B'.*Fil(:,n));
end

Give the command window command
dbstop if error
Run the code. When it stops, query
n
size(B.')
size(Fil(:,n))
size(fft(B'.*Fil(:,n)))
whos FFT
and tell us the results

You should be using functions... then you would not have to worry about the possibility of left-over arrays of incompatible size in local variables.
