power
(^,.^) power operation
Calling Sequence
t=A^b t=A**b t=A.^b
Arguments
 A,t
scalar, polynomial or rational matrix.
 b
a scalar, a vector or a scalar matrix.
Description
If
A
is a square matrix andb
is a scalar thenA^b
is the matrixA
to the powerb
.If
b
is a scalar andA
a matrix thenA.^b
is the matrix formed by the element ofA
to the powerb
(elementwise power). IfA
is a vector andb
is a scalar thenA^b
andA.^b
performs the same operation (i.e. elementwise power).If
A
is a scalar andb
is a matrix (or vector)A^b
andA.^b
are the matrices (or vectors) formed bya^(b(i,j))
.If
A
andb
are vectors (matrices) of the same sizeA.^b
is theA(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.
Examples
A=[1 2;3 4]; A^2.5, A.^2.5 (1:10)^2 (1:10).^2 s=poly(0,'s') s^(1:10)
