- O.k.... I've now completed:
-
- Spline interpolation
- Least Squares (interpolation)
- Lagrange (interpolation)
- Bezier
- B-spline
- LU decomposition with pivoting (linked with Spline & Least Squares)
- Matrix Solving : Ax=b ; via LU decomposition.
-
-
- These are going to be included in the final (PD) distribution of my Mathlib.
-
- Source & minimal documentation available for those algs on a "need to use
- urgently" basis by e-mailing to the below address
-
- P.s. no guarentees about the code until it is fully tested for the final
- distribution, but it works sufficiently well for limited useage at the moment.
