public class MnSimplex
extends MnApplication

SIMPLEX is a function minimization method using the simplex method of Nelder and Mead. MnSimplex provides minimization of the function by the method of SIMPLEX 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. As SIMPLEX is a stepping method it does not produce a covariance matrix.
