Particle Swarm Optimization code

I have this code for Particle Swarm Optimization (PSO) and the matlab shows this error :

First of all, I dont have equality constraints. Second there's an error shows: "Unrecognized function or variable 'PSO_non_linear_constraint'."

clc %clears the command window

clear all % clears the previous work space

close all % closes the privous graphical objects(figures)

That is not code that runs for the particleswarm function from Global Optimization Toolbox. You will have to ask the author of that toolbox any questions.
