7 Calling FFTW from Fortran

d@0: d@0:

d@0: This chapter describes the Fortran-callable interface to FFTW, which d@0: differs from the C interface only in the prefix (`dfftw_' instead d@0: of `fftw_'), and a few other minor details. The Fortran interface d@0: is included in the FFTW libraries by default, unless a Fortran compiler d@0: isn't found on your system or --disable-fortran is included in d@0: the configure flags. We assume here that the reader is already d@0: familiar with the usage of FFTW in C, as described elsewhere in this d@0: manual. d@0: d@0:
