How to determine whether the rule of an DynamicalSystem instance is inplace?

Specific Domains Modelling & Simulations
1

I would like to define a function that takes a DynamicalSystem ds as an argument and computes the Jacobian of dynamic_rule(ds) for further analysis. For this, it would be good to know whether dynamic_rule(ds) returns an inplace function or out-of-place. Is there such a functionality? Would it be safe to use m = first(methods(dynamic_rule(ds))) and then ask m.nargs==4 for and inplace function?

Check Base.hasmethod?

There is a function for that, ‘isinplace’ that operates on the dynamical system directly.

CU!
