`pysym `_ is an *experimental*
Python package for symbolic manipulation with limited scope (as in minimal).
It tries to stay compatible with the API of `SymPy `_.
It should be viewed as a prototype and not as a "production" package.

The capabilities include:

- Differentiation
- (slow) numerical evaluation (including "lambdify" support)

The above capabilities are exactly what is needed by
`pyodesys `_
and `pyneqsys `_.

Documentation
-------------
Autogenerated API documentation is found here: ``_
(and dev docs are here: ``_).

Installation
------------
Simplest way to install pysym and its (optional) dependencies is to use pip:

::

   $ pip install --user pysym pytest
   $ python -m pytest --pyargs pysym

or the `conda package manager `_:

::

   $ conda install -c bjodah pysym pytest
   $ python -m pytest --pyargs pysym

There are no requirements outside the Python standard library.

Source distribution is available here:
``_

Example
-------
Differentiation

.. code:: python

   >>> from pysym import Symbol, tan
   >>> x, y = map(Symbol, 'x y'.split())
   >>> expr = x*y**2 - tan(2*x)
   >>> print(expr.diff(x))
   ((y**2) - ((1 + (tan((2*x))**2))*2))


for more examples, see `examples/ `_, and rendered jupyter notebooks here:
