NonLinearKit

NonLinearKit is an interactive Java program which iteratively applies a non-linear RLS-type inversion using the Levenberg-Marquardt algorithm to obtain a stellar structure from a set of pulsation frequencies.

NonLinearKit was written by Daniel R. Reese and is derived from InversionKit. Marc-Antoine Dupret indirectly contributed to this code by explaining the Levenberg-Marquardt algorithm to Daniel Reese. It is one of the deliverables for the SPACEINN network, a major international collaboration funded by the European Commission's Seventh Framework Programme (FP7/2007-2013) under grant agreeement no. 312844.
