Example 1: Morris use-case and p-level input grid
=================================================

.. GENERATED FROM PYTHON SOURCE LINES 7-9

To define the trajectories, we suppose that the box :math:`[0,1]^{20}` is splitted into a p-level grid (p=5).
We set the number of trajectories input variables are randomly to 10.
