I'm writing a toolbox and packaging it as described in Create and Share Toolboxes. At the end of the installation process, I want to automatically run a script. Is this possible? We are trying to support MATLAB R2016a onward.

I include a function, which runs once the first time the toolbox is called instead. This is "after the installation", but not directly after the installation, but before the first run. I use ispref and setpref to set a flag, which is persistent between Matlab sessions. But it matters as which user you run the toolbox.

How do you handle this when there are many functions and classes in the toolbox? Do you just run the setup code at the beginning of every function?

If there are no "main functions", e.g. a GUI, this is not trivial. Adding a:
checkInstalled;
and
function checkInstalled
persistent runOnce
if isempty(runOnce)
runOnce = true;
callYourSetupRoutine;
end
end
takes about 0.5 seconds for 1e6 calls. But is this installation really required in all subfunctions?

Hello everybody, we have the same issue.
We build a custom library, which we want to distribute as a toolbox (.mltbx file). I want to simple run a custom Matlab script (.m file), when installing this toolbox with right-click -> Install.
What is the correct approach to this?
Thank you everybody and with best wishes,
Lars
