Greetings, Has anyone out there written a standard polynomial surface fitting routine similar to SFIT, but one that can handle irregularly gridded data, taking into account the x and y co'ords of the points to be fitted. I should think I could interpolate and scale the data to use with SFIT, or turn to Numerical Recipes, but if some one has done it already and would like to share... Many thanks, Justin PS I did have a look at the Los Almos WWW page and list of routines but with no luck.
