I’m trying to duplicate the first example of trajectory evolution in the docs for the InteractiveDynamcis package (Trajectory Evolution · InteractiveDynamics).
I’ve already created an environment into which I’ve added InteractiveDynamics, DynamicalSystems, GLMakie, OrdinaryDiffEq,
In that environment, I executed:
using InteractiveDynamics
using DynamicalSystems, GLMakie
using OrdinaryDiffEq
But when I try to execute next…
ds = Systems.henonheiles()
… I get error:
ERROR: UndefVarError: Systems not defined
Stacktrace:
[1] top-level scope
What is Systems?
I tried to add a package named Systems but no such package was found.
