Hi, let's say I have 2 graphs (2 arrays with numbers). They both look
different but are similar. I'm doing a FFT on one of the arrays and
then zero out some of the coefficients and then do an inverse FFT on
that array to try to get the 2nd array. When I plot the 2nd array and
the inverse one I get something similar to it but not close enough.
I've tried zeroing many coefficients but can't get anywhere. What
would be the best way to do this? Thanks.
