SymPy ===== A Python library for symbolic mathematics. http://code.google.com/p/sympy/ See the AUTHORS file for the list of authors. And many more people helped on the SymPy mailinglist, reported bugs, helped organize SymPy's participation in the Google Summer of Code, the Google Highly Open Participation Contest, wrote and blogged about SymPy... License: New BSD License (see the LICENSE file for details) covers all files in the sympy repository unless stated otherwise. 0. Download ----------- $ git clone git://git.sympy.org/sympy.git For other options (tarballs, debs, etc.), see the web page of SymPy. 1. Documentation and usage -------------------------- Everything is at: http://docs.sympy.org/ You can generate everything at the above site in your local copy of SymPy by: $ cd doc $ make html $ epiphany _build/html/index.html If you don't want to read that, here is a short usage: From this directory, start python and: >>> from sympy import Symbol, cos >>> x = Symbol('x') >>> e = 1/cos(x) >>> print e.series(x, 0, 10) 1 + (1/2)*x**2 + (5/24)*x**4 + (61/720)*x**6 + (277/8064)*x**8 + O(x**10) SymPy also comes with a console that is a simple wrapper around the classic python console (or ipython when available) that loads the sympy namespace and executes some common commands for you. To start it, issue: $ bin/isympy from this directory if SymPy is not installed or simply $ isympy if SymPy is installed somewhere in your PATH. 3. Tests -------- To execute all tests, run ./setup.py test in the current directory. For more fine-grained running of tests, use bin/test or respectively bin/doctest. 4. Clean -------- To clean everything (thus getting the same tree as in the repository): ./setup.py clean 5. Brief History ---------------- SymPy was started by Ondrej Certik in 2005, he wrote some code during the summer, then he wrote some more code during the summer 2006. In February 2007, Fabian Pedregosa joined the project and helped fixed many things, contributed documentation and made it alive again. 5 students (Mateusz Paprocki, Brian Jorgensen, Jason Gedge, Robert Schwarz and Chris Wu) improved SymPy incredibly during the summer 2007 as part of the Google Summer of Code. Pearu Peterson joined the development during the summer 2007 and he has made SymPy much more competitive by rewriting the core from scratch, that has made it from 10x to 100x faster. Jurjen N.E. Bos has contributed pretty printing and other patches. Fredrik Johansson has wrote mpmath and contributed a lot of patches. Since then, a lot more people have joined the development and some people have also left. You can see the full list in doc/src/aboutus.txt, or online at: http://docs.sympy.org/aboutus.html#sympy-development-team For people that don't want to be listed there, see the git history. 6.
