The interpolation of a dataset can be examined by polynomials, which is nice because polynomials are useful for complex curves approximations. In order to get the coefficients of the polynomial, since the dataset points are known, the below InterpolatingPolynomialCoefficients method can be used. This takes in a double array of tabulation points and polynomial points.
PLAIN [...]

The purpose of this method is to provide the faculty to calculate the second derivatives of a piecewise cubic polynomial with continuous first and second derivatives when there are known tabulation points. For more information on Spline interpolation you can view this article here. Naturally, this returns an typed double array containing the second derivatives [...]
