2D FFT (fast fourier transform) routine

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

For more complete information about compiler optimizations, see our Optimization Notice.

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.
