eval_chebyc
(n, x, out=None) = <ufunc 'eval_chebyc'>¶ Evaluate Chebyshev polynomial of the first kind on [-2, 2] at a point.
These polynomials are defined as
\[S_n(x) = T_n(x/2)\]where \(T_n\) 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_chebyt
.- xarray_like
Points at which to evaluate the Chebyshev polynomial
- Returns
- Cndarray
