orthopoly[P] - Legendre and Jacobi polynomials
Calling Sequence
P(n, a, b, x)
P(n, x)
Parameters
n
-
non-negative integer
x
algebraic expression
a, b
rational numbers greater than -1 or nonrational algebraic expressions
Description
The P(n, a, b, x) function computes the nth Jacobi polynomial with parameters a and b evaluated at x.
In the case of only two arguments, P(n, x) computes the nth Legendre (spherical) polynomial which is equal to P(n, 0, 0, x).
These polynomials are orthogonal on the interval with respect to the weight function when a and b are greater than -1. They satisfy:
The Jacobi polynomials are undefined for negative integer values of a or b.
Jacobi polynomials satisfy the following recurrence relation:
