error when call fun.

hi, I have this function: function [swarm]=initSwarm(N, N_PAR)

swarm = zeros(N,N_PAR);

for i = 1: N

    for j = 1: N_PAR

        swarm(i,j) = rand(1,1)%* ( V_MAX(j)-V_MIN(j) ) + V_MIN(j);

    end

end

when call it:

x=initSwarm(5,5);

I get this error, I don't know why?

??? Undefined function or method 'initSwarm' for input arguments of type 'double'.

Just add initSwarm.m in your MATLAB path and it will work.
