^ (power) Zkey

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.

4^2 ¸16

{a,2,c}^{1,b,3} ¸{a 2b cò}

expression ^ list1 ⇒ list

Returns expression raised to the power of the

elements in list1.

p^{a,2,ë3} ¸{pa pñ 1

pò}

list1 ^ expression ⇒ list

Returns the elements in list1 raised to the

power of expression.

{1,2,3,4}^ë2 ¸

{1 1/4 1/9 1/16}

squareMatrix1 ^ integer ⇒ matrix

Returns squareMatrix1 raised to the integer

power.

squareMatrix1 must be a square matrix.

If integer = ë1, computes the inverse matrix.

If integer < ë1, computes the inverse matrix

to an appropriate positive power.

[1,2;3,4]^ë1 ¸

[1,2;3,4]^ë2 ¸

Refers to the variable whose name is

varNameString. This lets you create and

modify variables from a program using

strings.
