public abstract TriangularMatrix<T> ExtractLowerTriangle(
MatrixDiagonal unitDiagonal = MatrixDiagonal.NonUnitDiagonal
)Parameters
- unitDiagonal MatrixDiagonal (Optional)
- If true, the matrix is unit triangular. Only the elements below the diagonal in the matrix are considered. If false, the diagonal elements of the matrix are taken as the diagonal elements of the triangular matrix.
Return Value
TriangularMatrix<T>A TriangularMatrix<T> whose elements are contained in the lower triangular portion of the matrix.
Exceptions
| Argument | the matrix is null. |
