My guess would be that data = {{1, 2}, {2, 3}, {3, 3}, {4, 2}, {5, 2}}; intfunc = Interpolation[data, InterpolationOrder -> 1] intfunc[2.5] would be about as efficient as you can get. (Of course it would probably be better to use a more sparse data table and higher order interpolation.) Jerry B. Keiper keiper at wri.com Wolfram Research, Inc.
