Re: Matrices,Matrix Non-Square Equations, Matrix Determinants, Linear Equations, Cramer's Rules, and
to perform G-J elimination using an application is actually computationally
there are better methods for what you want to achieve... i am currently at
work and i do not have any of my references with me, but if you contact me
via firstname.lastname@example.org i will provide you with the solution you are looking
