expression1 ^ expression2 ⇒ expression
list1
^ list2 ⇒ list
Returns the first argument raised to the power of the
second argument.
For a list, returns the elements in
list1 raised to the
power of the corresponding elements in
list2 .
In the real domain, fractional powers that have
reduced exponents with odd denominators use the
real branch versus the principal branch for complex
mode.

squareMatrix1 ^ integer ⇒ matrix
Returns squareMatrix1 raised to the integer power.
squareMatrix1 must be a square matrix.
If
integer = ë 1, computes the inverse matrix.
If
integer < ë 1, computes the inverse matrix to an
appropriate positive power.
