Request for Help in Matcont: Convergence problems fixed by misspellinghttps://sourceforge.net/p/matcont/discussion/762214/thread/ed0d6cf0/ Hi All, When I first try to run equilibrium from a known analytical solution, it says "Current step size too small (point 1)" However, if I first use the command "[x,v,s,h]=cont(@equilibrim,x1,v1,opt);" to get the error message "Undefined function or variable 'equilibrim'. " and then afterward use the correctly spelled command "[x,v,s,h]=cont(@equilibrium,x1,v1,opt);"...

Is there some way to get it to converge without having to first intentionally...

All of the examples that I have found in the TestSystems folder leave v0 undefined and let matcont cycle through the unit vectors to determine v0. Is there an example of an ODE definition file that defines the v0 vector rather than leaving it to be determined automatically? I don't know where or how it would be specified.
