First, load the CUDALink application:
Needs["CUDALink`"]This generates a random list of reals:
lst = RandomReal[1., {10}];This computes the one-dimensional Fourier transform using CUDA:
CUDAFourier[lst]The result agrees with the Wolfram Language:
Fourier[lst]CUDAFourier works on two-dimensional datasets. Here, a dataset is generated:
data = Table[Mod[Binomial[i, j], 2], {i, 0, 63}, {j, 0, 63}];Find the logarithmic power spectrum:
ArrayPlot[Log[Abs[CUDAFourier[data]]]]CUDAFourier can be used on multidimensional datasets. This gets the data from an image:
lst = ImageData[[image]];This performs the Fourier operation:
out = CUDAFourier[lst];This shows the absolute value of the result:
