Z key
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.

Returns expression raised to the power of the
elements in list1 .

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.
