Gaussian elimination method with MatLab
显示 更早的评论
Please how can I use MatLab to perform Gaussian elimination on the matrix
[1 2 3, 2 -1 -1, 3 2 1].
The answer for the above matrix extracted from the text book is
[1 2 -3, 0 -5 5, 0 0 6].

By the way, your "reduced" matrix reduces further to the 3x3 identity matrix.
