Pass the two variables in a handles structure when calling the second window. When the push button in the second window is then clicked call the variables from the handles structure and add them up.

enable option is in property inspector. but there is no enable command. I want to activate the pushbutton of second window by clicking the pushbutton of the first window automatically. Activating code must be written in first window pushbutton. plz plz help me.

set(GUIHandles.Pushbutton2,'enable','on');

now you just have to name the buttons and handles structures accordingly

The earlier responses will not accomplish what you are trying to do.

In order to activate (that is, execute) the callback of the second pushbutton when you press the first, you need to get the handle of the second pushbutton, and you need to get() the Callback of that pushbutton, and then you have to invoke that callback.

The exact mechanisms for invoking the callback once you have found it, varies according to how the callback was coded. If the callback was coded as a string (as tends to be the case when you use GUIDE) then you should use eval() to execute the string.

your answer is correct but mistakenly i accept another one. Sorry for that.

If you get() the callback and execute it in the manner I showed, then *all* appropriate parts of the callback will be executed. It would be tricky (but not impossible) for the callback to detect that it was being executed indirectly instead of directly because that button itself had been pushed.
