t3 = timer('TimerFcn', @authentic_wrapper, 'Period', 10, 'ExecutionMode', 'FixedSpacing');
start(t3);

First line is OK but after start function is says “??? Error while evaluating TimerFcn for timer ‘timer-1′
Too many input arguments.”

I have the .m file of the type function with the name authentic_wrapper in the same directory. What do I do wrong? Syntax seems to be right.

Thank you.

I know it is possible.

I can not think of an easy way to do that at the commend prompt. However, if you had a dialog box come up, you could set a timer to close it, and set a default value if needed.

@Nara,

It depends on the fidelity you want. How close to simultaneous do you want. If you are trying to get to hard real time, then you will want to look into Real Time Workshop.

You can set the period between starts, between completion and start, and other such variants. Between these and some creativity, I think you will be able to do whatever is needed.

Further to the previous post I discovered the pause function!

Would still be interested to know if you can have nested timers though.

Thanks,

Nice blog. Could you let me know if it is possible to set up a timer within a timer?

I have a function which is set up to run regularly (primary timer). Within that function I need Matlab to pause (secondary timer) between certain steps, so I set up a wait function as below. When I run the system, Matlab hangs. Maybe there’s a way to make Matlab pause without a timer?

function waitnow(length)

t_w = timer('StartFcn', 'disp(''waiting for refresh...'')', 'TimerFcn','disp(''waited'')','StartDelay',length);

start(t_w);

wait(t_w);

% stop(t_w);
