I just want to run my script within a certain time periodically. That's it all ....

Hi everyone, Nice to meet ya

I actually have a problem in my GUI design. My superior assign me to create a time scheduler script to create data periodically.

In the above GUI design, i want my toggle button of "Start FMI K-Indices Automation" do some work for a certain time. If the "Set Auto-Update Timer" was selected to "Per 3 Hour", so it meant my Script will run for every 00:00 AM/PM, 03:00 AM, 06:00 AM, ..... 18.00 PM, 21.00 PM, and 00 AM/PM again.

As far as i know, i just modified this script :

function [myTimer] = TimerScrip
myTimer = timer('Name','MyTimer',               ...
    'Period',5,                 ... 
    'StartDelay',0,                 ... 
    'TasksToExecute',inf,           ... 
    'ExecutionMode','fixedSpacing', ...
    'TimerFcn',@myTimerCallback); 
start(myTimer);

function myTimerCallback(~, ~)    
fprintf('hello!\n'); % This is actually filled by my actual script (FMI K-Indices) which ll create my 
% data automatically for every period (00:00 AM/PM, 03:00 AM, 06:00 AM,
% ..... 18.00 PM, 21.00 PM, and 00 AM/PM)

So if everyone here, know more about the script or maybe another powerful script to run my script periodically (hopefully without "Task Scheduler") and would lend me a hand to do so, I will be happy and grateful to receive it as my solving problem... Thank youu very muchh everyoneee...

and what is the problem? using a timer can be the right method if you dont close matlab. you only have to set the period to 3h = 3*60*60s =10800s

Ahh, yes, Sir. You may be right. But, if i set it when the time is 01:03 AM for instance, then the next time my script run will be at 04:03 AM, 07:03 AM, etc... I want it run at exatly in 00:00 AM, 03:00 AM, 06:00 AM, etc without waiting the time to 00:00 AM/PM or 03:00 or 06:00 AM or 09:00 AM first. So even if i start the timer in 02:00 Am, then the script will automatically run in 03:00 AM, 06:00 AM, 09:00 AM continuously.

@Tyann Hardyn: What precison do you require?

[Tyann Hardyn]

@Stephen23 I have not required time precision (plus minus second or minute), Sir... Please help me, Sir .....

Do you run time-consuming tasks on MATLAB and Simulink? Do you wish you could schedule them and run them in the background, unattended? How do you solve this question today?

Use

https://www.mathworks.com/help/matlab/ref/timer.startat.html

This is the function that lets you specify an absolute time for firing the timer.

[Tyann Hardyn]

Alright Sir Stephen @Stephen23, i ll try this
