If the explosive/implosive models were suitably normalized so that the solutions were stationary, then you might have a shot with global and perturbation methods. For the knife-edge unstable case, even...

On your first point, do I understand correctly that: levels / no r ---- NLsolve works when initialized from steady state with domain [ss*2, ss*0.01] levels / r ---- NLsove...

In general I think that the need for such transforms to keep variables positive is often symtematic of some other problem. In this particular case it's the cause of problems...

I have a multi-threading option for computing the weights, but I haven't tried to use CUDA or any GPU processing; this might be worth looking into in the future. The...

Thanks for letting me know. I'm happy for ChebyshevApprox to be faster and more useful to more people, so I would be interested to adopting some of your improvements. What's...

Hi Roberto, I have received and read your comment, but I haven't had time to look into it. I believe I know what you are referring to, however, but I'll...

Paul, I have been looking into the issue you raise. Are you able to send me a short model.txt file that illustrates the problem you are having? You are welcome...

Paul, out of interest, have you tried solving that model using a perturbation method? Can you please tell me what domain you are using for the approximation scheme. Posting the...

Roberto and Paul, I have tagged a new release v0.5.8 that I think addresses the two bugs you encountered. Thanks.
