CoupledODEs not defined

My CoupledODEs function suddenly stopped working. I have DyanamicalSystems Package installed. It is showing error:
“UndefVarError: CoupledODEs not defined”

Hey

That’s strange. Did you import it? Like

using DynamicalSystems

should work.

Otherwise, please try updating the package, like

using Pkg
Pkg.update("DynamicalSystems")
