I've got about 700 data points. They're arranged irregularly along arcs arranged in sort of truncated fan-shape. > Did you try the fitpack function bisplrep in scipy? Not recently. I spent a month or so wrestling with bisplrep a while back, but was unable to get stable results (either with real world data or with the example from the tutorial): http://www.visi.com/~grante/scipy/interpolate.html http://www.scipy.net/pipermail/scipy-user/2004-December/003921.html I switched to a trianguation scheme shortly after that posting, and haven't tired bisplrep since then. -- Grant Edwards grante Yow!
