how to compute a for cycle in copulapdf varying nu parameter from 1 to 8

I have to use copulapdf command and create different figures from it, varying the parameter nu from 1 to 8. The code for the copula pdf for the nu value=1 is:

nu=1;
r=0.5;
u = linspace(0,1,20);
[u1,u2] = meshgrid(u,u);
rho1 = copulaparam('t',r,nu);
y = copulapdf('t',[u1(:),u2(:)],rho1,nu);
surf(u1,u2,reshape(y,20,20))
xlabel('u1')ylabel('u2')

This script works but i want to find a way to have figures automatically for different values of nu. Can someone help me to write the for cycle for this purpose?

Not sure if this is what you want, but it looks easy enough. Change the first line to

for nu=1:8

add

end

as the last line. And insert

figure;

before the surf command.

Really thanks for the reply. I wrote this new code with your suggestion but Matlab gives me this error: "Expression or statement is incomplete or incorrect."

for 
  nu=1:8
   r=0.5;
  copulapdf('t',[u1(:),u2(:)],r,nu);
  u = linspace(0,1,20);
  [u1,u2] = meshgrid(u,u);
  figure;
  surf(u1,u2,reshape(y,20,20))
  xlabel('u1')ylabel('u2')
end

for nu=1:8

must all be on one line

now the error is:

xlabel('u1')ylabel('u2') | Error: Unexpected MATLAB expression.

LOL

Should be:

   xlabel('u1');
   ylabel('u2');

Very good, it works! really really thank you! The final script corrected is:

for nu=1:8    
    r=0.5;
    u = linspace(0,1,20);
    [u1,u2] = meshgrid(u,u);
    y = copulapdf('t',[u1(:),u2(:)],r,nu);
    figure;
    surf(u1,u2,reshape(y,20,20))
    xlabel('u1');
    ylabel('u2');
end
