Create an aggregated function
=============================

.. GENERATED FROM PYTHON SOURCE LINES 6-11

In this example we are going to build a function that stacks all the outputs from several functions

.. math::
   f = (f_1, \dots, f_n)


.. GENERATED FROM PYTHON SOURCE LINES 13-20

.. code-block:: default

    from __future__ import print_function
    import openturns as ot
    import openturns.viewer as viewer
    from matplotlib import pylab as plt
    import math as m
    ot.Log.Show(ot.Log.NONE)








.. GENERATED FROM PYTHON SOURCE LINES 21-22

assume a list of functions to aggregate

.. GENERATED FROM PYTHON SOURCE LINES 22-28

    functions = list()
    functions.append(ot.SymbolicFunction(['x1', 'x2', 'x3'],
                                         ['x1^2 + x2', 'x1 + x2 + x3']))

                                         ['x1 + 2 * x2 + x3', 'x1 + x2 - x3']))

create the aggregated function

.. GENERATED FROM PYTHON SOURCE LINES 30-32

.. code-block:: default

    function = ot.AggregatedFunction(functions)

evaluate the function
