I was able to continue the bifurcation curve of the saddle node of the limit cycles with "amplitude" 1e-1 Thank you so much for your help

Hello, I am trying to continue the saddle-node bifurcation curve of limit cycles from the generalized Hopf bifurcation. When starting the curve calculation, matcont freezes for several minutes and does not respond in any way. Then completes the curve calculation. When I check the calculated curve, I see only 1-10 points there. I've tried changing the fun tolerance, the test tolerance, and the var tolerance. Increasing the tolerance to 1e-04 caused the matcont hang to disappear, and the calculation...

Thank you for help

Hello, I see that there are no complex conjugate numbers with a purely imaginary part on the Hopf curve. I don't quite understand if this is really a Hopf curve or something else. Thank you for help

Hello I want to use the first Lyapunov coefficient to determine which branch of the Andronov-Hopf bifurcation corresponds to the supercritical and which to the subcritical I assume that h(5, :): HH is the first Lyapunov coefficient, but it's not entirely clear why it has such a name, shouldn't it be h(5,:): GH? My system is three-dimensional and HH bifurcation is not possible, but I see its name in the output table I guess it's actually GH, but I doubt it Thank you for help

Thank you so much for your help There is a message about this in the console I didn't pay attention to her before
