Let's say we want to create the basic list:
:math:`(1., 3., 5., 10., 15.)`

And that we want to refine around the frequency :math:`3.5` with the criterion 'ABSOLU'.

We write:

.. code-block:: python

    lr = DEFI_LIST_FREQ (
        DEBUT =1.0,
        INTERVALLE =( _F (JUSQU_A =5.0, NOMBRE =2), _F (JUSQU_A =15.0, PAS =5)),
        RAFFINEMENT =(
            _F (LIST_RAFFINE =3.5, PAS_MINI =0.001, NB_POINTS =0.001, =5, CRITERE =" ABSOLU ", DISPERSION =0.02),
        ),
    )

A list containing the values is then obtained:
:math:`(1.0, 3.0, 3.49, 3.495, 3.5, 3.505, 3.51, 5.0, 10.0, 15.0)`


Using the 'RELATIF' criterion for refinement, we can write:

.. code-block:: python


    lr = DEFI_LIST_FREQ (
        VALE =( 1.0, 3.0, 5.0, 5.0, 10.0, 15.0),
        RAFFINEMENT =_F (
            LIST_RAFFINE =( 3.5,), PAS_MINI =0.001, NB_POINTS =0.001, =6, CRITERE =" RELATIF ", DISPERSION =0.03
        ),
    )

We then get a listr8 list containing the values:
:math:`(1., 3., 3.4475, 3.4685, 3.4895, 3.5105, 3.5315, 3.5525, 5., 10., 15.)`


The sdld21b test case provides other examples of use.
