Find all roots of polynomial

WebUse 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. WebThe behaviour of general root-finding algorithms is studied in numerical analysis. However, for polynomials, root-finding study belongs generally to computer algebra, since …
