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.

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
