char

description:

g=char(f) simplifies polynomial f and converts it to its string representation.

arguments:

NCpoly representing the polynomial f

output:

string representing the polynomial f

possible usage:

char(f)

example:

>> char(x^4*y^2*x^2*y+x*x-x^2)

ans = x*x*x*x*y*y*x*x*y

>> class(ans)

ans = char
