Hi Mike.
I actually would expect the "help feedback" command to show the help for the @lti/feedback command if the control package is loaded.
If this is too complicated or just a nonsense, at least it should not lie saying that it has not yet been implemented.
I will check later what matlab does.

Hmm, it looks like the help function somehow knows that there must be a feedback function in the control package:

However, the help function is not clever enough to realize that 'feedback' has always been part of the control package (for at least a decade).

I assume that 'help' uses some kind of database which contains outdated/wrong information. This needs to be fixed.

Hi, thanks for your bug report. Can you explain what you think the correct behavior should be? It looks like it's working correctly to me, i.e. "help @lti/feedback" shows the help for the function.

Do you expect "help funcname" to look in every class definition for matching methods? Which one(s) take precedence? What does Matlab do?

In any case, this is not specific to the control package, updating bug info.

With the control package installed and loaded:
However the function is in the package and can be used. In fact "help @lti/feedback" returns the expected result:
