scipy.special.sh_jacobi(n, p, q, monic=False)[source]#

Shifted Jacobi polynomial.

Defined by

G_{n}^{(p, q)} (x) = {(\binom{2 n + p - 1}{n})}^{- 1} P_{n}^{(p - q, q - 1)} (2 x - 1),

$G_n^{(p, q)}(x) = \binom{2n + p - 1}{n}^{-1}P_n^{(p - q, q - 1)}(2x - 1),$

where $P_n^{(\cdot, \cdot)}$ is the nth Jacobi polynomial.

Parameters:

nint: Degree of the polynomial.
pfloat: Parameter, must have $p > q - 1$ .
qfloat: Parameter, must be greater than 0.
monicbool, optional: If True, scale the leading coefficient to be 1. Default is False.

Returns:

Notes

For fixed $p, q$ , the polynomials $G_n^{(p, q)}$ are orthogonal over $[0, 1]$ with weight function $(1 - x)^{p - q}x^{q - 1}$ .
