Module: fourier
| Description | Usage |
|---|---|
| tools for performing a 2D fast fourier transform of a function on a grid | |
| Authors: Edoardo Baldi and Gareth Tribello |   |
Details
The action in this module takes a function on a two-dimensional grid as input and computes a fourier transform upon the input function using FFTW. Currently, this actions performs a complex fourier transition even if the input data is real. The functionality here was developed and used in the paper cited below.
