Remarks
This method numerically factors the instance of the constructed matrix
A, where A is of type SparseMatrix and is
symmetric positive definite. The factorization is obtained in several
steps:
- First, matrix A is permuted to reduce fill-in, leading to
a sparse symmetric positive definite matrix
. - Then, matrix is symbolically and
numerically factored.
Note that the symbolic factorization is not done if the symbolic factor has been supplied by the user through the SetSymbolicFactor method.
Exceptions
| Exception | Condition |
|---|---|
| Imsl.Math..::.NotSPDException | is thrown when the input matrix is not symmetric, positive definite. |
