Simply add second number after that, do some sort of while/for/do-while/goto loop (ok, maybe only while or for :) ) and it should work. If you want more help, post your attempt (that is, attempt to read more matrices, not just one) Re: Matrices w/ Gaussian Elimination Programming Software Development by vavazoom Thank you :) The only problem I'm having now is more of a cosmetic issue. When I output my matrices, even though it outputs 0.00, I think in some cases it's not exactly 0. Because, some of them output as -0.00. Is there a way to fix this issue?
