One of my function generates some plots, and I want to set hold on or off at the end of the function.

If you just use "hold" it will toggle the hold state, so if hold is on, it will turn it off and vice versa.
"hold on" turns on the hold state and "hold off" turns it off.

There is no documented way of determining the original hold state, at least that I could find. Why do you feel you need to determine the original state? It's probably not necessary. You should know the way you want to leave your plot, and just set it accordingly.
