mpower

description:

g=mpower(f, n) is called for the syntax 'f^n' and means symbolic matrix power. So, it computes the n-th power of the (matrix of NCpolys) f, i.e., f^n.

arguments:

f is an NCpoly representing a polynomial or matrix of NCpolys with equal dimensions

n is a nonnegative integer

output:

NCpoly representing the polynomial f^n

possible usage:

f^n, mpower(f, n)

example:

>> [x*y+y,x;1,x+y]^2

ans = x+x*y*x*y+x*y^2+y*x*y+y^2   x^2+x*y+x*y*x+y*x

                      x+x*y+2*y   x+x^2+x*y+y*x+y^2
