As part of the Spectral Estimation Toolbox, some of our students had
similar requirements, but GSL didn't work then--I'm afraid I don't know
the exact reason[1]--and then used Armadillo and Fortran (which are not
standard libs for GNU Radio).
For the handling of small matrices (on the order of 64 x 64 and below),
Fortran actually worked best, faster than any other library.
