ChebPy is a Python implementation of `Chebfun <http://www.chebfun.org/>`_.

- The software is licensed under a 3-Clause BSD License, see `LICENSE.rst <LICENSE.rst>`_.
- For installation details, see `INSTALL.rst <INSTALL.rst>`_.
- The code is documented in various files in the `docs <docs/>`_ folder.


The figure above was generated with the following simple ChebPy code:

.. code:: python

    f = chebfun(lambda x: np.sin(x**2) + np.sin(x)**2, [0, 10])
    g = chebfun(lambda x: np.exp(-(x-5)**2/10), [0, 10])
    r = (f-g).roots()
    ax = f.plot(); g.plot()
    ax.plot(r, f(r), 'o')
