Create a function which interpolates a collection of $(x,y)$ samples.

Input parameters:

1. Sm → Two-dimensional samples to interpolate.
2. Al → Interpolation algorithm to use.
   • 0 → Nearest
   • 1 → Linear
   • 2 → Log-Linear
   • 3 → Cubic
   • 4 → Akima
   • 5 → Monotone
   • 6 → Bulirsch-Stoer
   • 7 → Equidistant
   • 8 → Floater-Hormann
   • 9 → Polynomial

Output parameters:

1. Fn → Interpolation function through a set of samples.
