Can you please help me check my code? It is outputting only the last value instead of all the values generated in for loop. Thank you.

a = 0.5;
b = 0.1;
E = 0.2;
v = 0.3;
Y= (E/(1-v^2));
ve = [1 v 0; v 1 0; 0 0 (1-v)/2];
uu = [-0.02 0.012 -1.23 0.2343 -0.124 1.111 0.214 0.453];
for i = 1:length(nu);
  for j = 1:length(eta);
   nu = -1:0.01:1;  
  eta = -1:0.01:1;
B(i,j) = [-(1-nu)/(4*a) 0 (1-nu)/(4*a) 0 (1+nu)/(4*a) 0 -(1+nu)/(4*a) 0;... 
  0 -(1-eta)/(4*b) 0 -(1+eta)/(4*b) 0 (1+eta)/(4*b) 0 (1-eta)/(4*b);...
  -(1-eta)/(4*b) -(1-nu)/(4*a) -(1+eta)/(4*b) (1-nu)/(4*a) (1+eta)/(4*b) (1+nu)/(4*a) (1-eta)/(4*b) -(1+nu)/(4*a)];
e(i,j) = B(i,j)*uu';
sig(i,j) = Y.*ve*e(i,j); % calculate the sig for each of the count and store it in sigsig
  end 
end
sigsig = [sig(i,j)]; % store all the sig here, each sig as a row vector

In the line

for i = 1:length(nu);

nu has not yet been defined.
