Automatically Run Script at End of Toolbox Installation

12 views (last 30 days)
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:
function checkInstalled
persistent runOnce
if isempty(runOnce)
runOnce = true;
takes about 0.5 seconds for 1e6 calls. But is this installation really required in all subfunctions?
