==================
SAGE Math Package
==================
.. warning:: Under progress!
This is a reference for the `sage <http://sagemath.org>`_ math package.
Web Notebooks
-----------------------------
To start run ``notebook()`` from an interactive shell; passing a directory as an argument will store files there. Also try``sage_wiki()``!
To get help on a ``cmd`` type ``cmd?`` in an cell and press the Escape key.
Interactive Shell
-----------------------------
Instead of the usual python ``**`` you can use ``^`` like the rest of the world, at least from the notebook and shell; use the old operator in scripts?
Prefacing with ``time`` gives processor time statistics; you can wrap a series of commands with ``t = cputime()`` and ``cputime(t)`` to get the sum of time statistics; ``walltime`` works similarly.
The general trick for saving text representations of objects is to open a file dscriptor and write the ``str`` of the object to it.
``save_session`` and ``load_session`` save all objects in the session to a ``.sobj`` file.
