Computes the symbolic factorization of a sparse Hermitian positive definite matrix.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.0.0

Syntax

C#
public void FactorSymbolically()
Visual Basic (Declaration)
Public Sub FactorSymbolically
Visual C++
public:
void FactorSymbolically()

Remarks

This method symbolically factors the instance of the constructed matrix A, where A is of type ComplexSparseMatrix and is Hermitian positive definite. The factorization is obtained in several steps:

  1. First, matrix A is permuted to reduce fill-in, leading to a sparse Hermitian positive definite matrix PAP^T.
  2. Then, matrix PAP^T is symbolically factored.

Exceptions

ExceptionCondition
Imsl.Math..::.NotSPDExceptionis thrown if the input matrix is not Hermitian, positive definite.
