[Boost-users] Function for Replace NaN with Zero and Vector2Vector Concordance

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. - Gundala Viswanath Jakarta - Indonesia
