Cubic spline, linear, nearest neighbor in that order of frequency.

A quick scan suggested this allows an N-D array of x input values,
whereas I want to evaluate a 1D array of x input values for 2- or N-D
array of y values - is that right?

Forgive my terrible ignorance, but is it easy to do cubic spline
interpolation using these classes?

Thanks for the reply,
