Hello Does it exist matrix data types in gnuradio ?

Probably not the way you think, but if you needed to perform a linear-algebra operation as part of a block’s work function, you could use numpy, if you write the block in python or a linear-algebra library if you are working in C++. Very Respectfully, Dan CaJacob ---

Hi Omar, you can have a look at the gr-specest toolbox. There are blocks using LAPACK in Fortran (MUSIC / ESPRIT) as well as examples using Armadillo (a C++ linear algebra library) to perform fast matrix computations. Cheers & happy hacking Moritz
