CUDAInverseFourier
CUDAInverseFourier[cuvec]
finds the discrete inverse Fourier transform of a CUDA vector cuvec.
CUDAInverseFourier[cumat]
finds the discrete inverse Fourier transform of a CUDA matrix cumat.
CUDAInverseFourier[list]
finds the discrete inverse Fourier transform of a list of complex numbers.
Details and Options
- The CUDALink application must be loaded using Needs["CUDALink`"].
- CUDAInverseFourier works on one-, two-, and three-dimensional lists.
Examples
Basic Examples (4)
First, load the CUDALink application:
Needs["CUDALink`"]This computes the one-dimensional inverse Fourier transform using CUDA:
res = CUDAInverseFourier[CUDAVector[{1, 0, 1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 1}]]The result agrees with the Wolfram Language:
Normal[Normal[res]] == InverseFourier[{1, 0, 1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 1}]CUDAInverseFourier works on two-dimensional datasets. Here, a dataset is generated:
data = CUDAMatrix[Table[Mod[Binomial[i, j], 2], {i, 0, 63}, {j, 0, 63}]];Find the logarithmic power spectrum:
ArrayPlot[Log[Abs[Normal@Normal@CUDAInverseFourier[data]]]]CUDAInverseFourier is the inverse of CUDAFourier:
res = CUDAInverseFourier[CUDAFourier[CUDAVector[ConstantArray[1. + 1I, 10]]]]Normal[Normal[res]]Text
