Function: triangularize (<M>) Returns the upper triangular form of the matrix `M`, as produced by Gaussian elimination. The return value is the same as `echelon`, except that the leading nonzero coefficient in each row is not normalized to 1. `lu_factor` and `cholesky` are other functions which yield triangularized matrices.

```          (%i1) M: matrix ([3, 7, aa, bb], [-1, 8, 5, 2], [9, 2, 11, 4]);
[  3   7  aa  bb ]
[                ]
(%o1)                  [ - 1  8  5   2  ]
[                ]
[  9   2  11  4  ]
(%i2) triangularize (M);
[ - 1   8         5            2      ]
[                                     ]
(%o2)        [  0   - 74     - 56         - 22     ]
[                                     ]
[  0    0    626 - 74 aa  238 - 74 bb ]```

There are also some inexact matches for `triangularize`. Try `?? triangularize` to see them.

```(%o1)                                true
(%i2) ```
