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:

This performs the Fourier operation:

This shows the absolute value of the result:
