in every file of toolbox i'm getting this error: Matrix dimentions must agree:
spec = fft(V.*hann(NFFT))/(NFFT*(nLev-1)/4);

when i checked sizes of individual term i got this:
>> size(hann(NFFT))
ans =
8192 1
>> size(V)
ans =
1 8192
i'm not getting why dot multiplication is been used? for getting 1D FFT transpose of 1st term should have been taken. Any help would be appreciated. Thanks in advance
