How make a multi for loop in parallel? See example below.
for i = 1:Nodex
for j=1:Nodey
nodpos_X((i-1)*Nodey+j,1) = (i-1) * delta + (delta / 2.0)*(-Nodex+1);
end
end

That already seems to be nested for loops. I notice that your right hand side does not involve j, so you will end up with multiple copies of the same value.

parfor ind = 1:Nodex*Nodey
[j,i]=ind2sub([Nodex,Nodey],ind);
nodpos_X(ind,1) = (i-1) * delta + (delta / 2.0)*(-Nodex+1);
end
