Hi all,
Does anyone know if an if-else can be used inside a timer? Like, I'm running a timer. I want that after 3 seconds, it checks to see if a condition is true and then executes the code block if it is so. Else, it should do something else. Is this possible?
I had this in mind: t = timer('TimerFcn', 'if n == 23 {do something} else {do something else} end', 'StartDelay', 3); start(t)
I would be thankful for any help.

Sure. But I don't know if the absolute elapsed time is available in the timer callback function (I doubt it), so you might have to use persistent variables (look it up) to keep track of that.
