WebbZeros and Recursion Theorem. Let fp n(x)gbe a family of orthogonal polynomials (indexed by their degree).The zeros of p n(x) are real, simple, and lie in the support of the weight function w(x). Proof. Let q n(x) have the odd-order roots of p n(x) as simple roots.Note that p n(x)q n(x) has no sign changes in the support [a;b] of w(x). Therefore, Z b a p n(x)q n(x) … Webb8 maj 2024 · By using roots () on symbolic variables, you can get four closed form expressions for the roots.
