Also, Tom Wickham-Jones has a very nice MathLink program that does this making a class of InterpolationFunction that does just what you need. It's from the 'ExtendGraphics' library of stuff that is part of his book on MMa Graphics. good luck In article <5tbe9f$j90 at smc.vnet.net>, elsner at avalon.msfc.nasa.gov (Ron Elsner) wrote: >I have data {x_i,y_i,f_i} and I wish to interpolate >between the grid points.
