Hi Max,
This is a very interesting suggestion, yet the main concern being that this
will limit the portability of the application but I believe it's worth to try
anyway.
Thanks,
Carlos

HI
As a POSSIBLE way to speed this up you might
see if it is possible to use DirectX for this. I'm not sure if it will
do the matrix sizes you need but you may be able to break them
down.
The advantage of using DirectX as far as I know
is that the matrix should be on on a very fast 3D graphics card designed for
the job????

Subject: [msvc] Matrix
multiplication
Hi all,
I have to multiply two matrices. The simple, brute force algorithm
works quite efficiently with small matrices (e.g. <100x100) but I need to
multiply matrices quite large > 2048 x 2048. Does anyone know any other
algoritm for matrix multiplication? The matrices can be non-square. The
Strassen algorithm seems to be a good method but if I remember correctly, it
does only work with square matrices (not 100% sure though).
Any help?
Regards,
Carlos
