MATLAB: Index out of bounds

genetic algorithmGlobal Optimization Toolbox

Hi I'm trying to execute a program but I keep getting this error:
"Attempted to access indx(1); index out of bounds because numel(indx)=0" I understand what it means, but I'm not able to fixe it, I need some help.
The main function is GAmodule and you can insert these numbers :
235
2
2
4
0
0
0
10
0
0
5
0
10
5
5
10
g
500
I got stuck in this error for 1 month and I will be very appreciate any help.

I don't have the Global Optimization Toolbox, but I went through your code and my first impression is that your problem could be here:
in FEM2.m line 45
 [Ex,Ey,Ez]=coordxtr(Edof,Coord,Dof,3);
reading through your documentation for coordxtr:
 nen:   number of element nodes
doesn't seem to me like you intend that number to be 3 for the above configuration.
Regardless, your code is most likely breaking here (at coordxtr):
       for j = 1:nen
          check=Dof(:,1:nend)-ones(n,1)*Edof(i,(j-1)*nend+2:j*nend+1);
          [indx,dum]=find(check==0);
          nodnum(j)=indx(1);
       end
So focus your attention on that.
