MATLAB: I’m trying to count the number of times the gui is being run on clicking a pushbutton. How to make the count continue even after the application is closed and started again. (i.e) if the count is 8 before closing ,it should start from 9 the next ti

guideiteration

I'm setting up the counter variables in the pushbutton callback and set the user data while the gui loads. \\before gui loads

set(handles.btnRun,'UserData',0)

\\PushButton CallBack

counter = get(hObject, 'UserData') + 1;

set(hObject, 'UserData', counter);

// As we are setting it to 0 , it is starting from 0 everytime. How to define a global varibale or something which can pass the previous count. //

Thanks for the help.

You may specify delete function which will be called each time application/gui is closed. Using this you may save all the variables you want to the file. Then using creation function you can bring those variables back. Read more about figure properties.
