Different result of MKL FFT between version 11.1.067 and 11.1.054

[paolo17]

Hello,

I've been using MKL 2D-FFT integrated in a Visual Studio 2005 with a Fortran Compiler version 11.1.067 wiith the following commands:

!For a matrix A(N1,N2)

L(1)=N1
L(2)=N2

! First time only:
Status = DftiCreateDescriptor( Desc_Handle, DFTI_DOUBLE, DFTI_COMPLEX, 2, L )
Status = DftiCommitDescriptor( Desc_Handle )

! For each Trasform:
status = DftiComputeForward ( desc_handle, A )


Now I've updated the Fortran Compiler to the version 11.1.067, but the results of the same case now is wrong. I checked the user guide but I didn't find any specific change about the commands to be used.

Thanks for help,
Paolo

Hi Paolo,

The two results may be different because inputs are different, amongother possible reasons.
