Dear All my apology for this question but i checked all documentaries and nothing found. i'm trying to compute inner dot of two computed vector which they are exactly similar to solution vector obtained in step-8 in tutorial i.e. each component of this vector have two index (in 2d) .for example if the ith component of solution vector is : solution(i) = (4.332 , 2.333) and i want to compute : (4.3 , 2.3).(4.3 , 2.3)=23.78 how could i do that or at least how i can access to information in every index of every component of this vector .
thanks, S.M.Mohseni
