Stop the iteration when a button got pressed in MATLAB App Designer

I'm currently developing an App which computes the roots for a given function, there is a solve button which computes the solution to the function, the output of each iteration will be presented in a table.

Now, I want to add a stop button which will stop the iteration whenever the stop button is preseed.

How can I call the stop button inside the start button to stop the iteration?

And what I have to add inside the stop function to make it work?

Here's the start button:

     fun = app.EditField.Value;
            a = app.EditField_2.Value;
            b = app.EditField_3.Value;
            error = 1.0*10.^-5;
            
            syms x;
            func = matlabFunction(str2sym(fun));
            devfunc = matlabFunction(diff(func(x)));
            
            if (app.EditField.Value == " " && app.EditField_2.Value == " " && app.EditField_3.Value == " " && app.EditField_4.Value == " ")
              %Error Alert
            else 
                fu = 1.0*10.^-5;
                
                num = 0;
                while ( abs(fu) >= error || num < 10)
                      num = num + 1;
              c = (a+b)/2;
              cr = c - func(c)/devfunc(c);
              if a < cr
                  xi = cr;
              else
                  xi = c;
              end
                fu = func(xi);
                
               if func(a)*fu < 0
                  b = xi;
                
                    vars = {num2str(num), num2str(xi),num2str(func(xi))};
                    app.UITable.Data = [app.UITable.Data; vars];
              
              else 
                  a = xi;
                 
                  vars = {num2str(num), num2str(xi),num2str(func(xi))};
                   app.UITable.Data = [app.UITable.Data; vars];  
                
               end       
                end
            end 
     
              app.Root.Text = num2str(xi);

Hi,

I would suggest using a “timer()” function within “StartButtonPushed(app, event)” method to execute.

Within the callback function of the timer object you can implement your functionality on calculating the roots of the equation.

When “StopButtonPushed(app, event)”method is called, you can delete or stop the timer.
