Using DFTI with a rectangular matrix

Once I found the problem, I did some digging and found the DFTI wrappers for the old FFT routines and rewrote my transform routines using the wrappers as a template (i.e. I copied it). Like my original code, the new one works fine for a square matrix, but generates the wrong solution for a rectangular one.

Has anyone else run across this problem before? Is there additional setup steps I need to do when m != n?

Any insight would be greatly appreciated.

Could you be more specific about what vesion of MKL do you use and what wrappers do you use?

There was a problem in fftw3

Thanks
