Syntax

public float ConditionNumber()

Public Function ConditionNumber As Single

public:
float ConditionNumber()

member ConditionNumber : unit -> float32

Single
An estimate of the reciprocal of the condition number.

Remarks

The condition number of a matrix A is:

kappa = ||A|| ||AInv||

where AInv is the inverse of the matrix A. This function returns an estimate of the reciprocal of the condition number, rho = 1/kappa.
