After two days fighting with IDL arrays vs. matrices, column major vs.
row major, transposition, leading dimensions and my own stupidity, I
finally got a DLM to encapsulate the CULA Tools single precision SVD
function. On my antiquated Nvidia GPU I get a sevenfold speedup relative
to LA_SVD for a 1000x2000 matrix. I'm asking Santa for a Fermi :-)

If you're interested, see

Cheers,

Mort
