WebInstead of including fftw3.f03 as in Overview of Fortran interface, you should include 'fftw3-mpi.f03' (after use, intrinsic :: iso_c_binding as before). The fftw3-mpi.f03 file includes fftw3.f03, so you should not include them both yourself. Web4.1.1 Complex numbers. The default FFTW interface uses double precision for all floating-point numbers, and defines a fftw_complex type to hold complex numbers as: Here, the [0] element holds the real part and the [1] element holds the imaginary part. Alternatively, if you have a C compiler (such as gcc) that supports the C99 revision of the ...
