Cvx/min find the position

Nonconvex

I need to find the minimum in an array containing a cvx Object and I am interested in finding its position, would it help if I edit the cvx/min fn. so that the position returned is this line becomes :
[vu pos] = sort( vr(all) );
instead of:
vu = sort( vr(all) );

and note that this isn’t the objective function, it’s just a step in the calculations.

You’re simply not using CVX properly. Please stop, until you fully understand the FAQ. In all likelihood, CVX cannot handle the models you are trying to solve.
