Re: BZSUPPORT: FFTW & Blitz

[Nicholas K. S. <nks...@lb...>]

Hello,
    We are combining FFTW & Blitz without any apparent problems.  One concern
is
to assure that your Blitz array is contiguous before handing it to the
Fourier
Transform.  So for example you declare

blitz::Array<double, 3> myBlitzArray;
/* ...  */
if (!myBlitzArray.isStorageContiguous()) {
    myBlitzArray.reference(myBlitzArray.copy());
}
/* Then you can recast the data C-style */
fftw_real* in = (fftw_real*) myBlitzArray.data();
