qin one polynomial and remainder is calculated using
divide(p,q). If the polynomials have more than one variable, an optional variable can be specified, which will be used for division.
gcd(p,q)returns the greatest common denominator of two expressions. Both functions also work with numbers as arguments.
>> divide(122344,7623) ans = [ 16 376 ] >> divide(2+i,3+2*i) ans = [ 1/2 1/2 ] >> syms x,z >> divide(x^3*z-1,x*z-x,x) ans = [ x^2*z/(z-1) -1 ] >> divide(x^3*z-1,x*z-x,z) ans = [ x^2 x^3-1 ] >> gcd(32897397,24552502) ans = 377 >> gcd(z*x^5-z,x^2-2*x+1) ans = x-1
