I don't understand the description / help-text for the
Why is there a new environment used?
And what is meant with an environment here?
Is it similar or the same as a local workspace,
like an environment in functional languages?
And why is it needed here?
numericDeriv could just calculate the difference bewtween two

but maybe in timeseries is a different value.
Can you please elaborate on that function?
Thanks In Advance,
