MatCont

MatCont is a Matlab software project for the numerical continuation and bifurcation study of continuous and discrete parameterized dynamical systems. Leaders of the project are Willy Govaerts (Gent,B) and Yuri A. Kuznetsov (Utrecht,NL) and Hil G.E. Meijer (UT, Enschede, NL).

In case you're stuck, use the forum, but to get a good answer provide:
1. What command do you give when this appears? Provide the exact steps. Stating "no convergence" is not enough.
2. Most procedures are explained in the Tutorials. There is a manual with detailed descriptions of the data.
