The DoubleHermPDTriDiagFact type exposes the following members.
Constructors Properties | Name | Description |
---|
| Cols |
Gets the number of columns in the matrix represented
by the factorization.
|
| IsGood |
Gets a boolean value which is true if the matrix
factorization succeeded and the factorization may be used
to solve equations, compute determinants, inverses, and so
on; otherwise false.
|
| IsPositiveDefinite |
Gets a boolean value which is true if the
matrix is positive definite and the factorization
may be used to solve equations, compute determinants,
inverses, and so on; otherwise false.
|
| Rows |
Gets the number of rows in the matrix represented
by the factorization.

TopMethods Remarks
The factorization has the form:
where
D is diagonal and
L is unit lower bidiagonal (
L'
is the conjugate transpose of the matrix
L).
