This is a Python implementation of the Faul-Goodsen-Powell algorithm which produces an interpolant for d-dimensional data using the multiquadric radial basis functions. It works well for even very high dimensional data.

Two parameters for the algorithm - q and c:

c>0, using a smaller value (O(10^-1) or smaller) is advised. This is the 'shape parameter' for the multiquadric.

q>0, using a value of q=30 is standard - feel free to go between 5 and 50. A rule of thumb is that smaller q means each iteration is quicker, but we may need more iterations for convergence overally.
