DoubleHermPDTriDiagFactFactor(DoubleComplexTriDiagMatrix, Boolean) Method

Factors the matrix A so that self represents the LDL' factorization of A.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public void Factor(
	DoubleComplexTriDiagMatrix A,
	bool estimateConditionNumber
)

Public Sub Factor ( 
	A As DoubleComplexTriDiagMatrix,
	estimateConditionNumber As Boolean
)

public:
void Factor(
	DoubleComplexTriDiagMatrix^ A, 
	bool estimateConditionNumber
)

member Factor : 
        A : DoubleComplexTriDiagMatrix * 
        estimateConditionNumber : bool -> unit

Parameters

A DoubleComplexTriDiagMatrix: The matrix to factor. The matrix is assumed to be Hermitian.
estimateConditionNumber Boolean: If true the condition number for the matrix will be estimated. This is a rather computationally expensive operation for large matrices.

Exceptions

Exception	Condition
MatrixNotSquareException	Thrown if the factored matrix was not square.

Remarks

Only the main diagonal and first subdiagonal of the matrix A are referenced and the main diagonal is assumed to be real. The imaginary part of the main diagonal and the superdiagonal of A are ignored.
