Completed 0 % ...Error using feval
Argument must contain a string or function_handle.
Error in Particle_Swarm_Optimization (line 103)
availability(p,itr)=feval(Food_availability,parameter);

Arudrha - according to the documentation for the PSO at the FEX Particle Swarm Optimization, the fourth input parameter must be a function of one variable. Pramit Biswas' example is of a function that accepts an array input as
function f = funfunc(array)
a=array(1);
b=array(2);
f = a+b ;
end
In your code, you are not passing a handle to a function but are instead passing the scalar value f.
