Why you don't use the same pointer arithmetic in C++? it's not easy because the data is hidden behind an abstraction
I though you wanted performances :)

have you compared with uBlas? i haven't yet uBLAS docs claim there is no abstraction penalty for relativly large matrices but i don't know with what kind of C code they compared, maybe it is inefficient by the same factor as ublas routines giving apparently no abstraction penalty
