How to make spline us C language

Splines requires far too much code to be answered here. Typically, if you do it from scratch, you will need code to work with matrix and polynomials or do it by hand. You will also have to select which contraints you want to apply to your spline.

In my case, I hace done it in C# using code found on the web for polynomial and matrix handling (well in fact, it was a simplified function to solve matrix in a tridiagonal form) and a mathematical book explaining spline and information found on the Internet was really helpful.

I suppose you want to draw a spline using the C language. You have at least two options:
1. Use a function from a library.
2. Write your own function, based on the spline equation (see, for instance, Wikipedia)[^] and using graphical primitives provided by your system.
