Syntax

void Preconditioner(
	double[] r,
	double[] z
)

Sub Preconditioner ( 
	r As Double(),
	z As Double()
)

void Preconditioner(
	array<double>^ r, 
	array<double>^ z
)

abstract Preconditioner : 
        r : float[] * 
        z : float[] -> unit

r: Type: SystemDouble
An input double array of length n generated during the implementation of the Solve method.
z: Type: SystemDouble
An output double array of length n.
