ILMathrank Method (InArraySingle, Single)

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

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

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

returnValue = ILMath.rank(A, tolerance)

Parameters

A

Type: ILNumericsInArraySingle
Input matrix:

tolerance (Optional)

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

Return Value

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

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