hat - (`^` ) exponentiation

### Calling Sequence

  `A^b`

### Description

Exponentiation of matrices or vectors by a constant vector.

If `A` is a vector or a rectangular matrix the exponentiation is done element-wise, with the usual meaning.

For square `A` matrices the exponentiation is done in the matrix sense.

For boolean, polynomial and rational matrices, the exponent must be an integer

Remark that `123.^b` is interpreted as `(123).^b` . In such cases dot is part of the operator, not of the number.

### Examples

    2^4
    [1 2;2 4]^(1+%i)
    s=poly(0,"s");
    [1 2 s]^4
    [s 1;1  s]^(-1)
