hello
I create a button in my figure and I want when I pushe the button it returns value of 1 in to a variable. I wrote this code but I couldn't get the Output Value.
f = figure;
ax.Position = [75 75 325 280];
c = uicontrol('Style','pushbutton','Callback',@(src,event)BinSet);
function Output=BinSet
Output=1;
disp('successfull')
end

Callback functions ignore output variables. If you want to do something with a value outside of the callback you need to store it elsewhere: the guidata, the appdata (setappdata and getappdata), or preferences (getpref and setpref).
For more advice about how to work with GUIs you can read the documentation or find helpful links here.

I highly encourage you to read the documentation for each of these functions and to check out the discussion I linked. The doc will explain how to use those functions, the thread will explain how to choose which you should use.
