Jampack

Class Inv

java.lang.Object

Jampack.Inv

public class Inv
extends java.lang.Object

Inv computes the inverse of a matrix.

Comments: Inv computes the inverse of A by using Solve to solve the system AX = I. This is inefficient, though not inordinately so. Eventually these methods will be replaced.
