GetLowerTriangularView(MatrixDiagonal)
public TriangularMatrix<T> GetLowerTriangularView(
MatrixDiagonal unitDiagonal = MatrixDiagonal.NonUnitDiagonal
)Parameters
- unitDiagonal MatrixDiagonal (Optional)
- A MatrixDiagonal value that specifies whether the diagonal elements are read from this matrix or treated as implied ones.
Return Value
TriangularMatrix<T>A TriangularMatrix<T> view whose stored elements are backed by the lower triangular portion of this matrix.
Remarks
The returned matrix shares storage with this matrix. Changes made through either matrix are visible through the other for elements that are part of the triangular view.
Exceptions
| Argument | rowCount is less than zero or greater than or equal to the number of rows in the matrix. -or- columnCount is less than zero or greater than or equal to the number of columns in the matrix. |

)Parameters
- rowCount Int32
- The number of rows in the TriangularMatrix<T>.
- columnCount Int32
- The number of columns in the TriangularMatrix<T>.
- unitDiagonal MatrixDiagonal (Optional)
- A MatrixDiagonal value that specifies whether the diagonal elements are read from this matrix or treated as implied ones.
Return Value
TriangularMatrix<T>A TriangularMatrix<T> view whose stored elements are backed by the lower triangular portion of this matrix.
Remarks
The returned matrix shares storage with this matrix. Changes made through either matrix are visible through the other for elements that are part of the triangular view.
