Mathchem python package
Presented by Mr. Alexander VASILYEV
Mathchem is a free open source Python package for calculating topological indices and other invariants of molecular graphs. For performance reasons we use here concept of lazy calculations. This means that we calculate data only when it is needed and then we save the results. Mathchem can be installed either as Python or as Sage module. Since the package contains no compiled code it is cross-platform and could be used in any operating system compatible with Python. The poster represents functionality of the package, its usage examples, installation process, structure and features with samples of code.
