This code is part of PSO Algorithm, in MATLAB. What is the type of empty_particle and particle? 

npop=100;

empty_particle.position=[];
empty_particle.velocity=[];
empty_particle.cost=[];
empty_particle.pbest=[];
empty_particle.pbestcost=[];

particle=repmat(empty_particle,npop,1);

empty_particle will be a structure which is then has entries initialised with a 0x0 array

They can either be created via the struct command

empty_particle = struct()
empty_particle.position=[];

or via matlab typecasting when you attempt to access an attribute 

empty_particle.position=[];

if you type whos into the command window it will tell you a lot about the workspace variables.
