Genetic Algorithm and Direct Search Toolbox

Example: Finding the Minimum of a Function

This section presents an example of using a pattern search to find the minimum of a function. This section covers the following topics:

• Objective Function
• Finding the Minimum of the Function
• Plotting the Objective Function Values and Mesh Sizes

Objective Function

The example uses the objective function, ps_example, which is included in the Genetic Algorithms and Direct Search Toolbox. You can view the code for the function by entering

• type ps_example
  

The following figure shows a plot of the function.
