ComplexSuperLU.SymmetricMode Property

ComplexSuperLUSymmetricMode Property

Specifies whether to use the symmetric mode.

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

Syntax

public bool SymmetricMode { get; set; }

Public Property SymmetricMode As Boolean
	Get
	Set

public:
property bool SymmetricMode {
	bool get ();
	void set (bool value);
}

member SymmetricMode : bool with get, set

Property Value

Type: Boolean
A bool indicating if symmetric mode is to be used.

Remarks

The symmetric mode option should be applied if the input matrix A is diagonally dominant or nearly so. The user should then define a small diagonal pivot threshold (e.g. 0.0 or 0.01) by property DiagonalPivotThreshold and choose an (

)-based column permutation algorithm (e.g. column permutation method SuperLU.ColumnOrdering.MinimumDegreeAtPlusA). SymmetricMode=true implies symmetric mode is used.

By default, SymmetricMode=false.
