Sort of. There are a number of curve-fitting modules available for Python as part of packages like ScyPy http://www.scipy.org/ and Scientific Python http://sourcesup.cru.fr/projects/scientific-py/ You generally have to provide the fitter with a function "template" for which it can find the coefficients. For example, you tell the fitter that you want a polynomial of the form f(y) = Ax^2 + Bx + C, and the fitter will find the values of A, B, C that best fit the data. There are also commercial products that have lists of hundreds of "templates" and will crunch through thme to find the ones that provide the best fits. -- Grant Edwards [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
