linking gui with coding

How can i link or interface my gui pushbutton with my coding on the command window. Example, when i click a pushbutton called the add function on the gui window, then the output will be sum of two values?

The output where?

If the output is just the display, then in the callback of the pushbutton call disp() or fprintf()

If the output is to be to the base workspace or to a variable that you could specifically request the value of, then see http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.3F

If the output needs to go into the "ans" stream of the command window and it is important that you not have to type anything at the command window, then the task gets more difficult. I think it could be done, but it would require using parts of MATLAB that are not well documented. Setting up a keyboard shortcut would be easier for this situation than clicking a button.

well the coding is written in m-file format where by typeing the file name in the command window and the output is just the display

[Walter Roberson]

function pushbutton1_callback(src, event, handles)
add() %use name of your function 
end

[Steven Chong]

name of my function will be the name of my m-file i saved as?

"well the coding is written in m-file format where by typeing the file name in the command window"

so use that file name where I used the example add()
