Smart Arrays LM (Levenberg-Marquart) Fit

What the package can do for you

The purpose of this package is to fit "experimental data" to a "fit function" representing a model for the experimental data. These must be specified as an array of x values and an an array of the respective y values.

This curve fitter is using the Levenberg-Marquardt algorithm. The Dart implementation here was derived from https://github.com/reptillicus/jsfit.

The major API functionalities

  • Available in the class LMfit.
  • Usage:
    1. call constructor
    2. call fit() or lmfit() ( = async version of fit())
