Interpolates a function on a rectangle.

Description

This is a very fast, vectorized, 2D extension of barycentric lagrange interpolation for a product grid on a rectangle. See included file for demonstration of how to use the script.

VERY GOOD!

[Ben Woodacre]

This is a good function, but it only works well for me when you have an odd number of sample points in X and Y and request interpolation to an even number of points in X and Y.

[Tiger Claws]

Very good. Works for odd and even number of sample points. Don't know what is the issue with the first review.
