MATLAB: Do I see the pop-up error “The parameter is incorrect” on MATLAB startup

MATLAB

Why do I see the pop-up error when I startup MATLAB?

The parameter is incorrect

Best Answer

This error is related to a corrupted MATLAB shortcut.

Launch MATLAB via the bin folder executable:

C:\Program Files\MATLAB\R20XXx\bin\matlab.exe

If this launches MATLAB without issue, then create a new shortcut with the exe.

MATLAB: Pop-Up menu help

Vlad - assuming that you are using GUIDE to create your GUI, suppose your five popup menus are named popupmenu1, popupmenu2,..., popupmenu5. If we assume that only numeric data has populated each of your popup menus, then the callback for your push button would look something like

 function pushbutton1_Callback(hObject, eventdata, handles)
 % get the list of items in the first popup menu
 menu1List = get(handles.popupmenu1,'String');
 % get the selected item in the first popup menu and convert to a number
 menu1Item = str2num(menu1List{get(handles.popupmenu1,'Value')});

You would then just repeat the above code for the remaining four popup menus and do whatever operation you need against them.

MATLAB: Value of Pop-up Menu

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.
