POW

POW

Usage:

POW A B

Inputs:

A	number or vector
B	number or vector

Outputs:

Y	number or vector (same type as A)

Function:

Compute A to the power of B.

if A and B are numbers:	Y = AB
if A is a vector and B a number:	Y[i] = A[i]B
if A and B are vectors:	Y[i] = A[i]B[i]

If A|A[i] is negative, B|B[i] must be an integer (automatic truncation of B)

If B|B[i] is negative, A|A[i] must be a nonzero value (otherwise result is set to 0)
