Find minimum of function using pattern search. x = patternsearch(fun,x0) finds a local minimum, x, to the function handle fun that computes the values of the objective function. x0 is a real vector specifying an initial point for the pattern search algorithm.

A pattern defines rules for matching text with text-searching functions like contains, matches, and extract. You can build a pattern expression using pattern functions, operators, and literal text.

This section explains how pattern search works for the function described in Optimize Using the GPS Algorithm. To simplify the explanation, this section describes how the generalized pattern search (GPS) works using the default maximal positive basis of …

In this tutorial, I show implementation of an optimization problem and solving it using Pattern Search in MATLAB. The given objective function is a simple fu...

To use your search method in a pattern search, give its function handle as the Custom Function (SearchFcn) option. Poll methods — You can use any poll method as a search algorithm in the "classic" algorithm. patternsearch conducts one poll step as a search.

patternsearch calls the objective function with just one argument x, but the parameterized objective function has four arguments: x, p1, p2, and p3. Use an anonymous function to capture the values of the additional arguments p1, p2, and p3.

Aug 5, 2016 · I am using patternsearch function in matlab. And my original code, [para,fv] = patternsearch(@(para)objective(para),para0,[],[], ... [],[],par_lb,par_ub,[],options); But now my objective function has multiple inputs, for example, object …

Apr 12, 2015 · pattern = [1 2 3]; out = cellfun(@(x) pdist2(x,pattern)==0,C); ind = find(out) Gives the same result as the other answer.

There are two patterns for each of the classes of direct search algorithms: the generalized pattern search (GPS) algorithm, the generating set search (GSS) algorithm, and the mesh adaptive direct search (MADS) algorithm.

This is a demonstration of how to create and manage options for pattern search using the PSOPTIMSET function in the Genetic Algorithm and Direct Search Toolbox.
