WebThe Fortran version of PSCF is an open-source program for using SCFT to describe spatially periodic structures formed by liquids containing block polymers. It is designed to treat incompressible liquids that may contain any mixture of linear block copolymers, homopolymers, and small molecule solvents. WebMar 3, 2010 · FFTW is designed to be called directly from C and C++, of course, and also includes wrapper functions allowing you to call it from Fortran. Several of our users have contributed code to make it easier to call FFTW from other languages as well: C# and .NET wrappers from the ILNumerics project .NET wrappers by Tobias Meyer.

http://www.fftw.org/fftw2_doc/fftw_6.html WebAs the title states I'm using FFTW (version 3.2.2) with Fortran 90/95 to perform a 2D FFT of real data (actually a field of random numbers). I think the forward step is working (at least I am getting some ouput). However I wanted to check everything by doing the IFFT to see if I can re-construct the original input. mistletoe is the state flower of what state
