Syntax

public void FactorSymbolically()

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