Function graph meshing
======================

.. GENERATED FROM PYTHON SOURCE LINES 7-8

In this example we will see how to define a function graph.

Define the surface equation

.. GENERATED FROM PYTHON SOURCE LINES 16-27

.. code-block:: Python

    a = [-4.0] * 3
    b = [4.0] * 3
    f = ot.SymbolicFunction(["x0", "x1"], ["cos(pi_*x0)*sin(pi_*x1)^2"])
    f.setInputDescription([r"$x_0$", r"$x_1$"])
    f.setOutputDescription([r"$x_2$"])
    inputInterval = ot.Interval(a[:2], b[:2])
