Programs for linear and non-linear least squares fitting

© Copyright 1998, Arthur G. Palmer, III.

The CurveFit program is a general fitting program designed for batch use. It can be used to fit R1 inversion recovery and R2 CPMG relaxation data for subsequent use in ModelFree, among other uses. It is available as a compiled executable for SGI and Linux computers. If you need access to source code or executables for other computer architectures, please contact Arthur G. Palmer (agp6@columbia.edu).
