Parameters
- matrix
- Type: Extreme.Mathematics.LinearAlgebraDenseMatrixT
A DenseMatrixT. - rowCount
- Type: SystemInt32
The number of rows in the
TriangularMatrixT. - columnCount
- Type: SystemInt32
The number of columns in the
TriangularMatrixT. - unitDiagonal
- Type: Extreme.MathematicsMatrixDiagonal
If , the matrix
is unit triangular. Only the elements below the diagonal
in matrix are considered. If ,
the diagonal elements of matrix are
taken as the diagonal elements of the triangular matrix.
Type Parameters
- T
Return Value
Type:
TriangularMatrixTA
TriangularMatrixT whose elements
are contained in the lower triangular portion of
matrix.
