% Usage: cheb (n, x) % % Returns the value of the nth-order Chebyshev polynomial calculated at % the point x. The Chebyshev polynomials are defined by the equations: % % / cos(n acos(x), |x| <= 1 % Tn(x) = | % \ cosh(n acosh(x), |x| > 1 % % If x is a vector, the output is a vector of the same size, where each % element is calculated as y(i) = Tn(x(i)).
