Hi tried generating the polynomial equation using excel sheet. It is very accurate and gives me exact polynomial equation. Is there any C# code to generate the polynomial equation for the given datapoints which gives the exact polynomial equation similar to the equation generated in excel. Please help me out to solve this problem.

Regards ,
Priya

The answer depends on 1) what kind of polynomials do you want to consider (powers, Chebyshev's, what?), 2) do you want to create a polynomial fitting the points exactly, or, considering the points as approximate values (with noise), optimize approximate fit?

This is one of the libraries you may want to use: https://numerical.codeplex.com[^].

Please see my comment to the question. First of all, you need to decide for yourself, what kind of mathematical problem should be solved.
