Preconditioner<T>.Rank Method

Definition

Namespace: Extreme.Mathematics.LinearAlgebra.IterativeSolvers.Preconditioners
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23

Overload List

Rank()	Returns the numerical rank of a matrix.
Rank(T)	Returns the numerical rank of a matrix using the specified tolerance.

Rank(T)

Returns the numerical rank of a matrix using the specified tolerance.

public override int Rank(
	T tolerance
)

Visual Basic

Public Overrides Function Rank ( 
	tolerance As T
) As Integer

C++/CLI

public:
virtual int Rank(
	T tolerance
) override

abstract Rank : 
        tolerance : 'T -> int 
override Rank : 
        tolerance : 'T -> int

Parameters

tolerance T: The absolute tolerance used to determine if a matrix component is considered zero.

Return Value

Int32
An integer indicating the numerical rank of the matrix.

Remarks

The method that is used to determine the rank, as well as the exact meaning of the tolerance, depend on the implementation. The tolerance is always relative to some norm of the matrix.
