Use timer to run script every ten seconds

I have a script that I want to execute automatically every ten seconds indefinitely until I tell it to stop. The script is called 'KelEdge'. I tried to figure out the code but I am having difficulty. Here is what I have:

function t = autoVIX()
t = timer;
t.StartFcn = @autoVIXstart;
t.TimerFcn = @runKelEdge;
t.StopFcn = @autoVIXCleanup;
t.Period = 10;
t.TasksToExecute = inf;
t.ExecutionMode = 'fixedRate';
end 

function autoVIXstart(KelEdge,~)
KelEdge;
end

function runKelEdge(KelEdge,~)
KelEdge;
end

function autoVIXCleanup(KelEdge,~)
disp('Stopping KelEdge.')
delete(KelEdge)
end

Thanks in advance for all the help.

It would be much better if you used fucntions instead of scripts. Functions have many advantages over scripts, e.g. encapsulation, abstraction, their own workspaces. It makes code easier to write and test when you use functions.

t = timer;
t.Period = 10;
t.TasksToExecute = inf;
t.ExecutionMode = 'fixedRate';
t.TimerFcn = @(src, event) run('KelEdge');

start(t)

I would recommend changing KelEdge into a function instead of a script. If you have it accept two arguments, then even if it ignores the arguments you could code as

t.TimeFcn = @KelEdge;

you cannot do this for a script because you cannot create a handle to a script, only a handle to a function.

Thanks...I don't understand the inputs to the timer function, I don't have a src or event, just a script...also when I run this, it runs infinitely i.e. it never stops and I can't stop it. What did I do wrong?

[Walter Roberson]

stop(t) to stop it.

You do have a script, but I recommend you make it a function instead.
