Blitz Support : |

Hi.
I am using (or rather trying to use) the fftw library in combination
with Blitz++.
I've learned that the arrays of complex data passed to fftw must be
16-byte aligned
to exploit the "Single Instruction Multiple Data" support of fftw.
Is there a way to make a Vector<complex<double> > be 16-byte aligned in
memory?
Until now, I used the fftw++ wrapper class by John C. Bowman in
combination with his
Array class (http://www.math.ualberta.ca/~bowman/Array.h) then created a
blitz::Vector
from preexisting memory by passing a pointer to an array of Bowman's
Array class.
But I am not that happy with this kind of "solution".
Any suggestions?
Best regards
Othmar
