Basic Examples   (3)
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 Mathematica:
works on two-dimensional datasets. Here, a dataset is generated:
Find the logarithmic power spectrum:
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:
