mtimes


description:
h=mtimes(f, g) is called for the syntax 'f * g' and means symbolic matrix multiplication.

arguments:
f and g are NCpolys representing polynomials or matrix of NCpolys with matching inner dimensions

output:
NCpoly representing the polynomial f * g

possible usage:
f * g, mtimes(f, g)

example:
>> f=[2*x*y,x];g=[x*y+x,y;y^2,x-y];
>> f*g
ans = 2*x*y*x+2*x*y*x*y+x*y^2   x^2-x*y+2*x*y^2
