Performing a Pattern Search

This section provides a brief introduction to the Pattern Search Tool, a graphical user interface (GUI) for performing a pattern search. This section covers the following topics:

• Calling patternsearch at the Command Line
• Using the Pattern Search Tool

Calling patternsearch at the Command Line

To perform a pattern search on an unconstrained problem at the command line, you call the function patternsearch with the syntax

• [x fval] = patternsearch(@objfun, x0)
  

where

• @objfun is a handle to the objective function.
• x0 is the starting point for the pattern search.

The results are given by

• fval -- Final value of the objective function
• x -- Point at which the final value is attained

Performing a Pattern Search from the Command Line explains in detail how to use the function patternsearch.
