Fourier transform grid!

[nandan_tandongmail_c]

Hi,

I am using the 2 dimensional forward transform and back transform routine of
MKL. I was wondering whether it is necessary to have the function
(for which the forward transfrom is evaluated) defined on
a orthogonal grid, or can it also be defined on a non-orthogonal grid?

Thanks in advance,

Regards,

Nandan.

Hi Nandan,

The two-dimensional FFT functions provided by Intel MKL compute the transform onthe data sampled on a rectangular grid. MKL doesn't support DFT on the data sampled hexagonally or otherwise non-rectangular.

Thanks
Dima
