Chebyshev-polynomials

C++ functions which evaluate Chebyshev polynomials

Chebyshev Polynomials of the first kind:
T₀(x):
template <class T> T T0(const T& x);

T₁(x):
template <class T> T T1(const T& x);

T₂(x):
template <class T> T T2(const T& x);

T_n(x):
template <class T> T Tn(unsigned int n, const T& x);

Chebyshev Polynomials of the second kind:
U₀(x):
template <class T> T U0(const T& x);

U₁(x):
template <class T> T U1(const T& x);

U₂(x):
template <class T> T U2(const T& x);

U_n(x):
template <class T> T Un(unsigned int n, const T& x);
