> Isn't it more efficient if there are many zeros in a given row? As I said before, there was a bug in it. They just returned the row of zeroes or vector of zeroes every time I call them, even if there were non-zero element in the rows and columns in question. Furthermore, as chris pointed out in [0], the inherited methods would be better since we can also use negative indices then.
