2D FFT (fast fourier transform) routine

Dear All

Hi

As I checked the MKL_lapack  examples and the lapacke Guide (http://www.netlib.org/lapack/lug/)  there is no FFT routine  in lapacke library.

1- am I right?

2- if yes how can I compute the 2D FFT of one matrix by lapacke?

Thanks in advande

1 - You are correct. LAPACK does not have FFT routines.

2 - MKL does provide a rich set of high performance FFT routines. Please take a look at the relevant chapter in the MKL reference manual: http://software.intel.com/en-us/node/470818. If you have installed MKL, you can find code samples of using MKL FFT in the "examples" folder.

Hi Zhang,

 

Could you help me to find a contact for a person responsible for the FFT library?

I have a major breakthrough in multidimensional FFT technology and I'd like to have an opporutunity to introduce it to Intel.

This will make the 2D/3D/nD FFT performance improve more than orders of magnitudes for large data sets.

You can find a brief introduction at: www.fouriertek.com.

I'd appreciate your kind help.

 

Thank you very much.

 

Regards,
