Indeed ;-)
Conclusion: Try the GSL, it's SVD methods should work quite fine. If you don't like gsl, try armadillo. If you're fine with fortran and LAPACK: Do it. Write a C header file for your Fortran functions and call them. Build a fortran shared library and link it to your c++ library. Do math. Really fast.
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, Moritz _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
