Interface jam.operator.Operator

public interface interface Operator
extends JamObject
An Operator is a function mapping one vector space to another.
This includes the case in which the range is the real numbers.
(Such a map from vectors to reals is traditionally called a functional).



An Operator could be a Vector (without the inner product), but currently is not because of certain implementation details.
We cannot see much of a benefit to uniting the Vector and Operator classes.
