PyDSTool is a sophisticated & integrated simulation and analysis environment
for dynamical systems models of physical systems (ODEs, DAEs, maps, and
hybrid systems).
PyDSTool is platform independent, written primarily in Python with some underlying C and Fortran legacy code for fast solving. It makes extensive use of the numpy and scipy libraries. PyDSTool supports symbolic math, optimization, phase plane analysis, continuation and bifurcation analysis,
data analysis, and other tools for modeling  particularly for biological applications.
The project is fully open source with a BSD license, and welcomes contributions from the community. Please visit the support pages at Sourceforge.net to post questions and feedback.
Support for Python 3.3+ and 64 bit OS platforms in v0.90! (2015)
These documentation pages are still under development. In the meantime, please feel free to ask questions on the support pages or email the developers. A custom site search is provided below.
