description: g=NCeval(f,subst) evaluates a polynomial f with substitutions defined in a row cell subst. arguments: f is an NCpoly representing a polynomial subst is a row cell of substitutions output: g is NCpoly where given substitutions are done in f possible usage: NCeval(f,subst) example: >> NCeval(x^2+x*y,{{x,x+y},{y,1}}) ans = x+x^2+x*y+y+y*x+y^2 >> NCeval(x^2+x*y,{x,[1 2;3 4]}) ans = 7+y 10+2*y 15+3*y 22+4*y |
