Hi all,
I’m using ROOT (5.15.08 ) under Windows XP. I would like make the FFT of some data.
The FFT.C example doesn’t work at now. I read from this forum that I should download the FFTW package. I’m wondering if I should download the precompiled Windows version or I have to compile it by myself.
And then, how can I tell ROOT where it is? I downloaded the precompiled ROOT for window, and thus I don’t know how to compile it with option “–with-fftw3-incdir --with-fftw3-libdir”, as it looks needed.
Can somebody help me?
many thanks!
