``sym`` provides a unified wrapper to some
symbolic manipulation libraries in Python. It makes it easy for library authors
to test their packages against several symbolic manipulation libraries.
Currently the following Python pacakges are available as "backends":
- `SymPy `_
- `SymEngine `_
- `PySym `_
- `SymCXX `_
- `Diofant `_
The capabilities exposed here are those needed by
- `pyodesys `_
- `pyneqsys `_
and include:
- Differentiation
- Numerical evaluation (including "lambdify" support)
see `tests `_
(and the development version for the current master branch is found here:
``_).
Installation
------------
Simplest way to install sym and its (optional) dependencies is to use pip:
::
$ pip install --user sym pytest
$ python -m pytest --pyargs sym
or the `conda package manager `_
Example
-------
Differentiation
.. code:: python
>>> from sym import Backend
>>> be = Backend('pysym') # just an example, use SymPy rather than pysym
>>> x, y = map(be.Symbol, 'x y'.split())
>>> expr = x*y**2 - be.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:
