Dear all,

I have two questions:

1. What's the way in Ublas to replace Nan with Zero,
    be it in Vector or Matrix?

2. What's the way to check vector 2 vector concordance.
   E.g. vector <int> V1 += 1,2,3;
          vector <int> V2 + =1,2,3;

    if we do  that_func(V1,V2), it will returns true.
