# scipy.special.sh_jacobi

scipy.special.sh_jacobi(n, p, q, monic=False)

  Shifted Jacobi polynomial.

  Defined by

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

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

  Parameters:
    n int

      Degree of the polynomial.

    p float

      Parameter, must have \(p > q - 1\).

    q float

      Parameter, must be greater than 0.

    monic bool, optional

      If True, scale the leading coefficient to be 1. Default is False.

  Returns:
    G orthopoly1d

      Shifted Jacobi polynomial.

  Notes

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