I need a subroutine of Fortran90 about "Fast Fourier Transform of a Step-function in 3-dimonsional."I use for FFT always the FFTW library (http://www.fftw.org/), which is
written in C but can easily be accessed from Fortran.
I read the related subroutines in Numerical Recipes Book, but I couldn't match it for a 3D step function.
Whould you please let me to have access to a subroutine for mentioned goal?
Otherwise: The is a bit off topic. The mailing list is for GNU Fortran
(gfortran) questions. For general Fortran questions I'd suggest to ask
in the comp.lang.fortran newsgroup, which can be also accessed via
