Interface jam.vector.Vector

public interface interface Vector
extends JamObject
A Vector is a mathematical vector with an inner product.


Warning: there is a potential conflict with java.util.Vector.
One should avoid using import java.util.*;
Import object from java.util on an individual basis, and never import java.util.Vector.
Instead use java.util.Vector in full where needed.
