[SciPy-user] ANN: sympycore version 0.1 released
Fri Feb 29 06:12:40 CST 2008
We are proud to present a new Python package:
sympycore - an efficient pure Python Computer Algebra System
Sympycore is available for download from
Sympycore is released under the New BSD License.
Sympycore provides efficient data structures for representing symbolic
expressions and methods to manipulate them. Sympycore uses a very
clear algebra oriented design that can be easily extended.
Sympycore is a pure Python package with no external dependencies, it
requires Python version 2.5 or higher to run. Sympycore uses Mpmath
for fast arbitrary-precision floating-point arithmetic that is
included into sympycore package.
Sympycore is to our knowledge the most efficient pure Python
implementation of a Computer Algebra System. Its speed is comparable
to Computer Algebra Systems implemented in compiled languages. Some
comparison benchmarks are available in
and it is our aim to continue seeking for more efficient ways to
manipulate symbolic expressions:
Sympycore version 0.1 provides the following features:
* symbolic arithmetic operations
* basic expression manipulation methods: expanding, substituting,
and pattern matching.
* primitive algebra to represent unevaluated symbolic expressions
* calculus algebra of symbolic expressions, unevaluated elementary
functions, differentiation and polynomial integration methods
* univariate and multivariate polynomial rings
* matrix rings
* expressions with physical units
* SympyCore User's Guide and API Docs are available online.
Take a look at the demo for sympycore 0.1 release:
However, one should be aware that sympycore does not implement many
features that other Computer Algebra Systems do. The version number
0.1 speaks for itself:)
Sympycore is inspired by many attempts to implement CAS for Python and
it is created to fix SymPy performance and robustness issues.
Sympycore does not yet have nearly as many features as SymPy. Our goal
is to work on in direction of merging the efforts with the SymPy
project in the near future.
