What is better?What is the added value by using 2D multi index container vs. vector<vector<T> >? Can anyone explain me the difference quickly?Thanks for helpPshemek

Hello Pshemek, I don't really know what a 2D multi-index container is supposed to be or how can one devise a multi-index structure comparable with a vector<vector<T> >. Aren't you by chance referring to Boost.MultiArray? http://boost.org/libs/multi_array/doc/index.html This lib does indeed provide data structures resembling vector of vectors in a number of ways, while being more efficient and providing nicer syntax and extended functionality.
