MATLAB: Genetic Algorithm with Array as variable

gagenetic algorithmMATLAB and Simulink Student Suiteoptimization

So say I have some array at the beginning of a very long code. And at the end the program outputs a single value. How do I get the genetic algorithm tool to change the values of each element in the array to minimize the output value? This may be something simple but I cannot find a method or example on how to do this. Thanks for your time!

All you have to do is change your array to a row vector, something like this:
 input = x(:)';
Here x represents your array of variables (known as decision variables) that the optimizer changes to minimize the output value (known as the objective function or, for ga, the fitness function). Then input is the set of variables that ga evaluates for finding a minimum.
See this example of constrained minimization for help.
Good luck,
