ILMathrank Method (InArrayDouble, Double)

public static long rank(
	InArray<double> A,
	double tolerance = -1
)

Public Shared Function rank ( 
	A As InArray(Of Double),
	Optional tolerance As Double = -1
) As Long

Dim A As InArray(Of Double)
Dim tolerance As Double
Dim returnValue As Long

returnValue = ILMath.rank(A, tolerance)

Parameters

A

Type: ILNumericsInArrayDouble
Input matrix:

tolerance (Optional)

Type: SystemDouble
[Optional] Threshold below which a singular value is considered zero. Default: (-1) auto.

Return Value

tol = length(A) * norm(A) * eps

• length(A) - the longest dimension of A
• norm(A) - the largest singular value of A, see: svd(InArrayDouble),
• eps - the distance between 1 and the smallest next greater value.
