Hi,
I'm using FFTW library to do my FFT calculation.
My sample size is so large to get the resolution I want ( >10^7
samples). It's time and memory consuming.
Since I'm just interested in the first 1000 or 10000 points in the
fequency domain. So custom functions will be so useful to me and I can
only calculate the first some points I want.
Here comes the problem. I found no C source code in the FFTW package
even after it's compiled. and I need to find out souce codes of
functions I called and I can rewrite them. Does anyone know how to do
this?
Thank you.
