Use the poly function to obtain a polynomial from its roots: p = poly (r) . The poly function is the inverse of the roots function. Use the fzero function to find the roots of nonlinear equations. While the roots function works only with polynomials, the fzero function is more broadly applicable to different types of equations.

If solve cannot find a solution and ReturnConditions is false, the solve function internally calls the numeric solver vpasolve that tries to find a numeric solution. For polynomial equations and systems without symbolic parameters, the numeric solver returns all solutions.

By convention, MATLAB ® returns the roots in a column vector. The poly function converts the roots back to polynomial coefficients. When operating on vectors, poly and roots are inverse functions, such that poly (roots (p)) returns p (up to roundoff error, ordering, and scaling). p2 = poly (r) p2 = 1 -1 -6
