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)

%% constrained function with equality and inequality contraints
fun=@(x)1.1*x(1) + 1.2*x(2) + 2*x(3) + 1.3*x(4) + 3*x(5);

constraints=@(x)[-8*x(1) - 2*x(2) - 15*x(3) - 4*x(4) - 30*x(5) + 60;

nvars=5; % number of variables to be optimized

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.
