Releasing SimPers software for computing persistence under simplicial maps

We are happy to announce the release of the software SimPers that  can compute topological persistence of a sequence of simplicial complexes connected with SIMPLICIAL MAPS. We hope that this will fill the need for computing persistence under maps more general than inclusions. The software has been developed by the computational geometry/topology research group at CSE, OSU based on the  paper:

Computing topological persistence for simplicial maps
T. K. Dey,  F. Fan, and Y. Wang., (SoCG 2014), Proc. 30th Annu. Sympos. Comput. Geom. (2013).
