CUDAFourier
CUDAFourier[list]
finds the discrete Fourier transform of a list of complex numbers.
CUDAFourier[mem]
finds the discrete Fourier transform of a CUDAMemory.
Details and Options
- The CUDALink application must be loaded using Needs["CUDALink`"].
- CUDAFourier works on one-, two-, and three-dimensional lists.

First, load the CUDALink application:
This generates a random list of reals:
This computes the one-dimensional Fourier transform using CUDA:
The result agrees with the Wolfram Language:
CUDAFourier works on two-dimensional datasets. Here, a dataset is generated:
Find the logarithmic power spectrum:
CUDAFourier can be used on multidimensional datasets. This gets the data from an image:
