Wanted: C# programming library for mathematics

Question

What I need is: plots creation, stuff for interpolation, stuff for counting such things as

and

where L(x) is an interpolation built from some data (points) generated from original known function f(x). meaning we know original function. we have a range (-a, a) - known. We need library to help us calculate data points in range. we need to calculate L(x) a polinom using that data in that range.

I need this library to be free and opensource

Answer 1

Perhaps Math.NET can help you.
