Notifications when a Simulink block parameters change

Hi,

is it possible to get notifications when the parameters of Simulink blocks are changed, and if it is, how?

I was hoping that event listeners would be of help, but they seem to be specific to simulation.

When are you looking to be notified? Are you using source control?

I'd simply like to have a Matlab function called whenever a parameter is changed so that I can react on the change.

I think this is possible for Mask parameters using dialog callbacks as described on this blog post, but don't know that it's possible for regular block parameters. You should probably create a mask for all the blocks that you want to configure with such a callback.

Thanks for your answer, but unfortunately, creating a mask for every block inside a model is very tedious and is not really an option for me.

I was hoping for a solution along the lines of get_param/set_param: (e.g. a function notify_when_param_changes(param, func)). Ideally, the solution would not involve GUI in any way.

Ivan: Unfortunately, I don't think this is currently possible. Please feel free to confirm this with MathWorks Tech Support and submit an enhancement request.
