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
