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:

This computes the one-dimensional inverse Fourier transform using CUDA:

The result agrees with the Wolfram Language:

CUDAInverseFourier works on two-dimensional datasets. Here, a dataset is generated:

Find the logarithmic power spectrum:
