I've no idea. I had never done anything with splines before,

I've got about 700 data points. T

How many x,y,z points do you have?
Did you try the fitpack function bisplrep in scipy? It can work well as
long as

I need to interpolate an irregularly spaced set of sampled
points: Given a set of x,y,z points, I need to interpolate z
values for a much finer x,y grid.
I tried using the scipy sandbox delaunay module, but the
interpolators don't work: the natural neighbor interpolator
produces a surface with "ho
