cmatrix.Matrix.triangular

Matrix.triangular()

Test if the matrix have a triangulare profile.

Returns

int

Test if the self matrix is triangular.

In case of, returns code are given :

• 0 => no triangular

• 1 => inf triangular

• 2 => sup triangular

Examples

>>> m=rand(4)
            >>> n=m.triangle(0)
            >>> o=m.triangle(1)
            >>> print(n)
