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]

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:
CUDAInverseFourier is the inverse of CUDAFourier:
