Your push button should have a "Callback Function" generated within the code.
You need to set the "tag" properties of your editable text boxes (There is a tag by default too, but creating a tag is good practice)
If you do not know how to do that, let me know.
After you have the tag properties set, you can call the information that the user entered in the editable text boxes.
Say the tag of your first text box is "input1" and the second is "input2"
The code you would use is
input1str = get(handles.input1, 'String');
input2str = get(handles.input2, 'String');
After this code runs, input1str and input2str are strings of what were entered in the editable text boxes.
If you need them as numbers, use the following code afterwards
input1num = str2num(input1str);
input2num = str2num(input2str);
All of this is happening in the pushbutton callback, and it will activate when you press the button.
Now under the push button callback after this, you can add to the code to do whatever you want with those to inputs. For example, you add them together.
answer = input1num + input2num;
Now if you want to display this answer to the screen, you should add a static text box to your GUI to display it in, or you can make it pop up using the msgbox command.
Say you set the 'tag' property of your static textbox to "answerbox"
The code you would then need to use is
set(handles.answerbox, 'String', answer)
Remember, all of this code should be under the pushbuttons callback, and it all runs when you press the push button.
Let me know if I should clarify anything!
