power

power — power operation (^,.^)

Calling sequence

t=A^b  
t=A**b  
t=A.^b

`A,t`	: scalar, polynomial or rational matrix.
`b`	:a scalar, a vector or a scalar matrix.

`(A:square)^(b:scalar)`	: If `A` is a square matrix and `b` is a scalar then `A^b` is the matrix `A` to the power `b`.
`(A:matrix).^(b:scalar)`	: If `b` is a scalar and `A` a matrix then `A.^b` is the matrix formed by the element of `A` to the power `b` (elementwise power). If `A` is a vector and `b` is a scalar then `A^b` and `A.^b` performs the same operation (i.e elementwise power).
`(A:scalar).^(b:matrix)`	If `A` is a scalar and `b` is a matrix (or vector) `A^b` and `A.^b` are the matrices (or vectors) formed by `a^(b(i,j))`.
`(A:matrix).^(b:matrix)`	If `A` and `b` are vectors (matrices) of the same size `A.^b` is the `A(i)^b(i)` vector (`A(i,j)^b(i,j)` matrix).

Notes:

- For square matrices A^p is computed through successive matrices multiplications if p is a positive integer, and by diagonalization if not.

- ** and ^ operators are synonyms.
