template<typename ArrayType = Eigen::ArrayXd>
struct CoolProp::superancillary::ChebyshevApproximation1D< ArrayType >
A set of multiple Chebyshev expansions covering an interval [xmin, xmax]. This is a 1D approximation. Practically speaking the independent variable is temperature, but the code was left generic to highlight the generiticity of the approach
At construction, the independent variable is subdivided into portions that are each monotonic in the dependent variable, to facilitate later rootfinding in domains that are therefore known to be monotonic, and therefore invertible
