Re: [Discuss-gnuradio] maxtrix inverse

Well you could implement your Matrix inversion using VOLK, of course.

But to my knowledge you'd have to write the necessary kernels yourself.

Can we replace Eigen with VOLK in some extent?

Hi BZS,

Eigen is a pretty good library. Other's that might come to might is
using blas/lapack in fortran or armadillo. I wouldn't expect too much
of a speedup when compared to Eigen though. For examples on how to use
fortran or armadillo with GNU Radio look at the gr-specest out of tree
module.

Cheers,

Moritz
