I download the matrix module from CPAN , http://search.cpan.org/doc/ULPFR/Math-Matrix-0.3/README, $a = new Math::Matrix ([rand,rand,rand], [rand,rand,rand], [rand,rand,rand]); , but I am still at lost as to how to construct a matrix so if I want to construct 1, 2,3, 1, 1, 1, 2, 3, 4 can I say : $a = new Math::Matrix ([1, 2, 3], [1, 1, 1], [2, 3, 4]); thanks! -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
