I want to get value as a number from pop-menu. for example if user want to select gender. 1 for male and 2 for female. i have create this code
function gender_Callback(hObject, eventdata, handles)
gender = (get(hObject, 'Value'));
switch gender
case 'Male'
gender = 1;
case 'Female'
gender = 2;
end
% Save the new n value
handles.gender = gender;
guidata(hObject,handles)
and this for get value
gender = handles.gender;
but it's result not 1 or 2, but strange number (e.g 212.0060). what's wrong and how the correct code. thank you very much

get() does not return the word in the popup list, it returns the index. So the whole switch statement is not even needed. Actually the function is not even needed so I'm not sure why you're using it. Anytime, in any function, that you need the gender number, simply do this
gender = get(handles.gender, 'value');
No switch needed, no code in the popup's callback needed, all that is needed is the line above. Use it anywhere that you were incorrectly going to use gender=handles.gender. That code was incorrect because that was giving you the handle (a floating point number) rather than the number you thought.

The code should be
gender = (get(hObject, 'Value'));
switch gender
case 1
%do
case 2
%do
end
