\sa MatrixBase::coeff() * \warning the coordinates must fit into the referenced triangular part */

restrict coeff accessors to 1x1 expressions. No need to care about mutators here since this isnt a Lvalue expression

\returns an expression of the \a i-th column of *this. Note that the numbering starts at 0. * * Example: \include MatrixBase_col.cpp * Output: \
