- `C = power (A, B)`

Return the element-by-element operation of `A` raised to the `B` power.

This function and `A .^ B` are equivalent.

If several complex results are possible, returns the one with smallest
non-negative argument (angle). Use `realpow`, `realsqrt`, `cbrt`, or `nthroot`
if a real result is preferred.

See also: `mpower`, `realpow`, `realsqrt`, `cbrt`, `nthroot`.
