Reference for Solution Value

Hi, I am looking at solving optimizaton problems using MATLAB to model the problem and CPLEX as the solver. Everything works and I am able to get my solution. However lets say I have 3 optimization variables all of different sizes, when I obtain the solution, I get the values of all the variables in 1 variable which I now have to sought through to get the values for each inidivual variable. Now if I were doing this in python and one of my variables is x, I would just use value.x to get the value of the x variable. Is there a similar way to get the values for the individual optimization variables without have to manually sought it out myself. This is what I use to obtain my solution:

options = cplexoptimset('cplex');
options.timelimit = 300;
[sol3,fval3, exitflag3, output3] = cplexmiqp(PP.H, PP.f, PP.Aineq, PP.bineq, ...
    PP.Aeq, PP.beq,[], [], [], PP.lb, PP.ub, ctype, [], options);       

If I had 3 optim. variables x1, x2 and x3 which are not scalar but arrays, my solution is stored in sol3 as [x1 x2 x3]. I want to just reference each variable without doing it manually.
