Divide two polynomials using MATLAB

Question

I want to divide p(x) by q(x) given that:

p(x)=-5x^4+3x^2-6x
q(x)=x^2+1

I tried:

p=inline(\'-5*(x^4)+         


        

Answer 1

r = sym(p) \ sym(q) would do the trick. The result would be a symbolic function, of course. To convert that to inline, s = inline(r).

Edit: As for the "WHY": you cannot divide two inline functions. Instead, they must first be converted to their symbolic representation.
