You can use a persistent variable to keep track of the number of times the callback was called:

persistent NumberOfCalls
if isempty(NumberOfCalls),NumberOfCalls=0;end
NumberOfCalls = NumberOfCalls+1;

TotalNumberOfTasks = 3;
NumberOfCalls = mod(NumberOfCalls,TotalNumberOfTasks);
switch NumberOfCalls
    case 1
        % do something
    case 2
        % do something else
    case 0
        % do something different
end

Lets take a example - I am working in MATLAB APP Designer . I want a single edit field and a single button, once i press button, edit field should show (1). Next when i press the same button edit field should show (2). In this way same button with two task when pushed one after other two times.

Then you need to put this code in the callback for the button.

Your description seems easy enough to implement. '% do something' would become code that sets the String property of your edit field to '(1)', while '% do something else' would become code that sets the String property of your edit field to '(2)'.

What exactly is your question?

Once Button is pressed it will execute complete callback code as per you. How case will take now button is pressed i need to execute case 1 and now again button is pressed i need to execute case 2. How to take NumberOfCalls value increment only when button is pressed
