cubic_splineDescriptionProduces a reference to a subroutine which evaluates a C^2 piecewise cubic polynomial passing through the specified points : (x0,y0), ... Syntax
Params References to two arrays, specifying respectively the x, y values to be interpolated by the Hermite polynomial. All of the parameters are required. There are no defaults. The x values must be strictly increasing. Returns A reference to a function of one variable representing the polynomial. The domain of the function is the closed interval spanned by the x values used in its definition. Notes Cubic splines are often used to represent numerical data.
