Class Jampack.Inv

java.lang.Object
   |
   +----Jampack.Inv

public class Inv
extends 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.
