scipy.special.eval_sh_chebyu

scipy.special.eval_sh_chebyu(n, x, out=None) = <ufunc 'eval_sh_chebyu'>

Evaluate shifted Chebyshev polynomial of the second kind at a point.

These polynomials are defined as

$$U_n^*(x) = U_n(2x - 1)$$

where $U_n$ is a Chebyshev polynomial of the first kind.

Parameters:

n : array_like

Degree of the polynomial. If not an integer, the result is determined via the relation to eval_chebyu.

x : array_like

Points at which to evaluate the shifted Chebyshev polynomial

Returns:

U : ndarray

Values of the shifted Chebyshev polynomial
