Thank you very much Vasil for your response.
I already had that. But I keep getting the same problemI was looking at
module as an example

However, in this example I need to remove this line; otherwise I get error.
But I still

One of the possible reasons
Thank you again for your responses.
I installed Armadillo, BLAS, and LAPACK. Armadillo seems to be working,
since I can do basic operations with matrices using it

Thank you all so much for the detailed responses, really appreciate it.
To give some background, my application is to build a CCA (canonical
correlation analysis) filter as an OOT C++ block. And the inputs are two
digital signals (represented as matrices) - one of them I receive and
decode real
True, Eigen is pretty popular for people needing to do Matrix
operations – I wasn't aware they even have Matrix decompositions[1]!
(in hindsight... considering the library name...)
I like Eigen, but there's two caveats, I find:
1. indexing is done with () instead of [] (I guess it's made for
Hi Laura,
Just to add to the suggestions, I've seen Eigen [1] used in the past.
It's a template library (headers only) and has no external
dependencies other than the standard library and that might be
something to consider given your use-case.

Hi Laura, Marcus,
for small processors (e.g. the beaglebone, used for KiwiSDR GPS
position solutions) I have adapted an old library originally developed
by NIST,

Oh not to forget: if you really just want to use LAPACK in isolation
and not require other dependencies at runtime... there's of course also
the option of writing Fortran [1] and then just directly using it from
C++... but beware, FORTRAN matrices are column-major, whereas C/C++
tends to be
So, that depends a bit on what you want to do:
These operations are classically implemented in a library called
LAPACK, which is really mature (and, it's written in Fortran90). You
use it through C++ wrappers like "IT++" or "Armadillo".
Be a bit careful though. The usual way of defining the
Hi Laura,
Armadillo is a common c++ lib for linear algebra. gr-doa makes use of it.

Hi all,
Is there any library to use in gnuradio for algebra operations, such as
matrix eigenvalues, and pseudoinverse? Or I'd need to code them myself in
C++?
I need to integrate those operations into my OOT C++ blocks.
Thanks for your time
Best
