Indeed ;-)

Umhhhh ...I agree with, use GSL if it works for you. However I have to 
say that the upstream armadillo code does weird stuff for matrices < 
64x64 (they propose their own matrix multiplication algorithm which for 
our case was _horribly_ slow).

As Martin pointed out, see the SpecEst Toolbox on how to do stuff wit 
CMake. If you'd rather use autotools, contact me off list, I should 
still have the project lying around somewhere.

I also started the gr-linalg toolbox back in 2009, but never had the 
time to work on it. It has an example for SVD though, however I haven't 
tried it since ages ... might need some tweaking, might be even broken...

Cheers and happy hacking,
