working with matrix

[Ramón T. B.]

Hello,

   how could I do for working with matrix filled with mpz_t numbers? I say, for doing (math) matrix multiplications for example. It is possible or I need another library outside de gmp?

   I refer to those matrix operations like that (http://www.gnu.org/software/gsl/manual/html_node/Matrix-operations.html) in the gsl library.

Best regards and thanks in advance: framontb
