SparseCholesky.FactorSymbolically Method

SparseCholeskyFactorSymbolically Method

Computes the symbolic factorization of a sparse real symmetric positive definite matrix.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0

Syntax

public void FactorSymbolically()

Public Sub FactorSymbolically

public:
void FactorSymbolically()

member FactorSymbolically : unit -> unit

Exceptions

Exception	Condition
NotSPDException	is thrown when the input matrix is not symmetric, positive definite.

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.
