Hi,
I have separate m-file which generates numeric value once a second and I want to pass this value to GUI once a second. How can I pass this variable to GUI from separate m-file and update it at second intervals?
I have tried many things but haven't succeed yet. Please help if you can.

I believe that you have a m-file which is a function having either a timer function or a loop to generate the numeric value. You will need to pass the handle to the GUI to this function in the m-file and then set the value of the text box.
  1. Set the 'Tag' property in the GUI code for the text box So that we can identify the text box.
  2. Pass the handle to the GUI to your function which generates the numeric value
  3. Access the text box using the "findobj" function in your function. Something like this tb = findobj(figHandle,'Tag', tagvalue)
  4. Set the text to the numeric value. Something like this set(tb,'String',numeric_value)
I hope this helps with your issue. If this is not what you are expecting I would suggest contacting MathWorks Technical Support with more clarification on your workflow.

Hi Rutuja,
Can you help clarify the steps for me even further? I'm a beginner and I'd like to do this same thing.
My .m timer function is:
function timer
for i = 1:15
clc;
i;
pause(1)
end
And the tag for my textbox is text2. I'd like to push a pushbutton and have the timer show up on the textbox.
Thanks!
