Welcome to Dionysus' documentation!
===================================

Dionysus is a C++ library for computing persistent homology. It provides
implementations of the following algorithms:

The C++ API is currently very poorly documented. One's best source for its
documentation is its usage in various :ref:`examples` (located in
:sfile:`examples/`).

The :ref:`Python bindings <python-bindings>` provide both a simple interface to
the low-level C++ functionality as well as high-level auxilliary routines. Their
"thinness" is meant to provide the efficiency benefits of C++ together with the
simplicity, elegance, and interactivity of Python. Since they mimick the C++
functionality, their documentation may be a helpful resource for the latter.
