 POWER  POWER Matrix Power Operator


Usage
 
 The power operator for scalars and square matrices.  This operator is really a 
 combination of two operators, both of which have the same general syntax:
 
   y = a ^ b
 
 The exact action taken by this operator, and the size and type of the output, 
 depends on which of the two configurations of a and b is present:
   1.  a is a scalar, b is a square matrix
   2.  a is a square matrix, b is a scalar
