Here is a matlab wrapper for the c++ code from Nicolas Bonneel available on this page, which is a light adaptation of LEMON to solve the network simplex for bipartite graphs. I recommend using the source code, but you can also use one of the system specific compiled matlab function.
- Corrected a bug that appears for highly degenerated problem that made the optimality check fail (leading to infinite cycling)
- Added an argument that allows to limit the maximum number of simplex pivot (defaults to infinity)
- Coming soon
