CurveFit

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).
