power - Array power
Syntax
Z = X.^Y
Description
Z = X.^Y denotes element-by-element powers. X and Y must
have the same dimensions unless one is a scalar. A scalar is expanded to an
array of the same size as the other input.
C = power(A,B) is called for the syntax 'A
.^ B' when A or B is an object.
Note that for a negative value X and a non-integer
value Y, if the abs(Y) is less than
one, the power function returns the complex roots. To
obtain the remaining real roots, use the nthroot function.
