window pop up 1

[chopieske]

Hello all,
I was wondering if there existed a block in Simulink that when a condition is satisfied, a window pops up with a message I would define.
Thank you in advance.

Yes, there is. Or more accurately, when a condition is satisfied you can enable a block to display a box with a message in it.

Here's the pseudo code

If condition==satisfied
then
MSG$="OMG it works!!!!"
messagebox(MSG$)
else
endif

This may need some banal refinements, but frankly let's face it, you should have done Business Studies.








Cheers

Actually I was asking for block in Simulink, not MatLab code.

I'll try to be more specific:
I need to stop a simulation either when it finishes (obviously) or when a signal exceeds a certain value (for which I use a RELATIONAL OPERATOR block and a STOP block). It would be helpful to show a message if the simulation has stopped because of that value exceeding the limit imposed. (This model is going to be used by people when I'm not working here anymore so I won't be able to explain them.)
My question is if there is such a block in Simulink that when that condition is satisfied, a window or some kind of message pops up saying why the simulation has stopped. I would put this block parallel to the STOP block.

Would you GregLocock (or anybody else) be able to help again? Thank you.
...and please, don't be misrespectful.

Cheers

Nevermind, I already found it after 2 days of intensive search.

In case it can be of any help to somebody, it is a block called ASSERTION. It stops the simulation, shows an error window and writes whatever message in the Command Window.

That'll teach me to be snarky, I hadn't realised there was no messagebox function as such. I'd have written some m code long before finding 'assertion'.
