The reason why I don't use the MKL routines for FFTW is because I was not able to make them work, do you know if there is some example code out there with Fortran calling these routines?Thank you,Alessandro 0 Kudos Copy link Reply TimP Honored Contributor III 07-06-2009 06:...
I use vs2013+ivf2013 program my fortran code, The FFTW2 wrappers to Intel MKL provide the following subroutines for calling from Fortran: call

We have compared manyC and Fortran implementations of the DFT on several machines,and our experiments show that FFTWtypically yields significantlybetter performance than all other publicly available DFT software.More interestingly, while retaining complete portability, FFTW iscompetitivewithor fasterthan...

exampleconvr3.cc Local transpose (in-place or out-of-place): exampletranspose.cc More general types of convolutions (for example, autoconvolutions) can be performed by defining a custom multiplier function. Wrappers Wrappers for the convolution routines are available for C, Fortran, and Python....
