Howdy, I maintain the Math::GSL CPAN [0] module and recently a user asked me how to calculate the square root of a n×n positive-semidefinite real matrix A. I browsed through the GSL documentation and did not immediately find anything. Is there a way to do this currently with GSL?
Thanks, Duke [0] - http://search.cpan.org/dist/Math-GSL/ -- Jonathan "Duke" Leto [email protected] http://leto.net
