NAME

 53_ffts

DESCRIPTION

 This directory contains level-2 routines related
 to Fast Fourier Transform within the ABINIT package.
 Most come from the Corning version of Stefan Goedecker's package,
 written in F77 in 1994, and have been translated
 to F90 and ABINIT's style.
 The two entry points to ABINIT FFTs are fourwf.f and fourdp.f .
 The indexing of planewaves on the FFT grid is also done
 by routines in this directory :
 boundy.f, indfft.f and kgindex.f .
 The more recent 2002 version of Stefan Goedecker's FFTs
 are contained in Lib_fftnew
