public class MnMigrad
extends MnApplication

MnMigrad provides minimization of the function by the method of MIGRAD, the most efficient and complete single method, recommended for general functions, and the functionality for parameters interaction. It also retains the result from the last minimization in case the user may want to do subsequent minimization steps with parameter interactions in between the minimization requests. The minimization produces as a by-product the error matrix of the parameters, which is usually reliable unless warning messages are produced.
