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