How to generate my custom copula data?

Hello!

When I calculate the copula using copulatif :

uu = ksdensity(x,x,'function','cdf');   
vv = ksdensity(y,y,'function','cdf'); 
[Rho,nu] = copulafit('t',[uu vv],'Method','ApproximateML');

I can calculate a random correlated data set using copularnd:

r = copularnd('t',Rho,nu,3100);                          
uu1 = r(:,1);
vv1 = r(:,2);

Is there a way to calculate vv1 given new data?

After copulafit on my known data(uu) I want to use the copula to fit vv1 given uunew where :

uunew = ksdensity(xnew,xnew,'function','cdf'); 

instead of building a random sequence:

vv1=func('t',Rho,nu,uunew);  

Thank!
