Remarks
This method symbolically 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 factored.
Exceptions
| Exception | Condition |
|---|---|
| Imsl.Math..::.NotSPDException | is thrown when the input matrix is not symmetric, positive definite. |
