I have had success using armadillo matrix inversions within GNURadio. The
only thing you need to be careful of is that when you install the library
you need to ensure that you install the hardware accelerated versions of
BLAS and LAPACK; I have seen this result in a 200 X slowdown. For a 64*64

No, but it would be nice to have a kernel for that.
The caveat is that V
Well you could implement your Matrix inversion using VOLK, of course.
But to my knowledge you'd have to write the necessary kernels yourself.

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.

hi,
when i deal data in my block,i want to scramble the positions symbol in a
frame,and at receiver-end descramble these symbols,get correct the order,for
this purpose,i need to compute the inverse of 64*64 matrix,and when i used the
eigen library ,it works slowly wnen compare with the deal
