[Blitz-support] Introducing CVMLCPP: a library that works with Blitz++

[Fokko B. <fpb...@gm...>]

Dear Blitz++-users,

Please allow me to introduce CVMLCPP, a library that offers some nice
features such as an easy front-end to the FFTW, convolution &
correlation, but also a voxelizer. With minimal effort, it is usable
with Blitz++: only some wrappers are needed.

Example:

#include <cassert>
#include <algorithm>
#include <base/BlitzArray>
#include <signal/Fourier>

using namespace cvmlcpp;

// Have a blitz++ array
blitz::Array<int, 3> a(3, 4, 5);
std::fill(a.begin(), a.end(), 7);

// Create a wrapper around "a" for cvmlcpp-compatibility
BlitzArray<int, 3> ba(a);
assert( (3*4*5*7) == std::accumulate(ba.begin(), ba.end(), 0));

// Create output and a wrapper
blitz::Array<std::complex<double>, 3> a_fft(3, 4, 5);
BlitzArray<std::complex<double>, 3> ba_fft(a);

// Compute 3D-Fourier tranform with "fftw"
doDFT(ba, ba_ffft);

The BlitzArray<..> class is usable as a regular blitz::Array, it is just
a subclass providing some glue.

The library has been tested with gcc 4.1 / 4.2 and blitz 0.9, all as
provided on Ubuntu 8.04.

Should you be interested, the CVMLCPP is available (under GPL) here:

Specific information about the use of Blitz++ / CVMLCPP:

A more extensive example can be found here:

Of course I hope you find the CVMLCPP library useful, and if not, please
do excuse the spam. Comments, suggestion, critique and patches are
welcome, but please do understand that my time is somewhat limited. As
usual, the use of this code is entirely on your own risk.

Best regards,
