What I envisioned was that M[i,:] would return a row_vector and M[:,j] would return a column_vector, because this would be symmetric behavior. M[i], by convention, would behave the same as M[i,:].
Can you please be explicit about the value added by that convention, as you see it? Thank you, Alan Isaac PS I assume your "vector" class would always accept a single index, for both row and column vectors? What is the return type of v[i]?
