Curve Fit Bench
Model library
442 models, written by physicists.
Each one carries starting values read from your data and, where physics demands it, bounds. Numerical models — the BCS gap equation, Bloch–Grüneisen and Debye integrals, WHH, Callaway — are solved properly rather than approximated.
Missing the model your analysis needs? We write custom models and verify them on synthetic data the same way as the library. Request a model or see plans.
