Hello!
Is it possible to get the frequency out of diagram via a Fourier Transformation in ROOT? If yes, how?
thanks, Jonas
Hi,
you can use the FFT classes in ROOT based on the FFTW package, available from ROOT v 5.12
See the tutorial FFT.C in $ROOTSYS/tutorials
To use it you need also to install first the fftw package
(from www.fftw.org) and re-configure root with options
–with-fftw3-incdir --with-fftw3-libdir
Best Regards
