plus

description:

h=plus(f, g) is called for the syntax 'f + g' and means symbolic addition.

arguments:

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

output:

NCpoly representing the polynomial f + g

possible usage:

f + g, plus(f, g)

example:

>> f=[x^2-2*x*y,1-x];g=[x*y,x];

>> f+g

ans = x^2-x*y   1
