module | modulefft |
This module contains fast fourier transform wrappers. We use the convention of the FFT without any prefactor (just like FFTW), This implies that the inverse transform of the transform gives the original sequence times the number of gridpoints, i.e. FFT^+[FFT^-[x]]= N*[x]. | |
Functions/Subroutines | |
subroutine | modulefft::get_FFT1D (instruction, length1, vec, INFO) |
This is the FFTW3 wrapper for the 1D fft. | |
subroutine | modulefft::get_FFT2D (instruction, length1, length2, vec, INFO) |
This is the FFTW3 wrapper for the 2D fft. | |
subroutine | modulefft::get_FFT3D (instruction, length1, length2, length3, vec, INFO) |
This is the FFTW3 wrapper for the 3D fft. |
