Iterators

We provide :ref:`iterators<Iterator>` supporting standard **cpp** syntax:

.. code-block:: cpp

    /* basis is Basis class instance */

    /* Using begin() and end() */
    for(auto it = basis.begin(); it < basis.end(); ++it){
        std::cout << *it << std::endl;
    }

    /* Using first() and last() */
    for(auto it = basis.first(); it <= basis.last(); ++it){
        std::cout << *it << std::endl;
    }

.. warning::

   The :ref:`iterator<Iterator>` initiated by ``end()`` does **not** point to a physical state.
