Three programs to compute the values of the Gegenbauer polynomials C(n, a, x), renormalized Gegenbauer polynomials C(n, x) and Jacobi polynomials P(n, a, b, x) at x. The Jacobi polynomials are a generalization of the Gegenbauer polynomials, which in turn are generalizations of Chebyshev and Legendre polynomials. |
