i've popupmenu having entries as
2 4 8 16 32 64 128
i want when user selects '2' , this string value convert to 2 as number so that i can use it in variable and i can use it in my mathematical calculations.
i tried following code….
str = get(handles.popupmenu3,'String'); val = get(handles.popupmenu3,'Value'); switch str{val}; case '2' a = get(handles.popupmenu3,'String'); a1 = str2num(a); b = get(handles.popupmenu3,'String'); b1 = str2num(b); case '4' a = get(handles.popupmenu3,'String'); a1 = str2num(a); b = get(handles.popupmenu3,'String'); b1 = str2num(b); case '8' a = get(handles.popupmenu3,'String'); a1 = str2num(a); b = get(handles.popupmenu3,'String'); b1= str2num(b); case '16' a = get(handles.popupmenu3,'String'); a1 = str2num(a); b = get(handles.popupmenu3,'String'); b1 = str2num(b); case '32' a = get(handles.popupmenu3,'String'); a1 = str2num(a); b = get(handles.popupmenu3,'String'); b1 = str2num(b); end
same for other cases like 64 and 128…
when i run this i got the error:
Error using str2num (line 33)Requires string or character array input.
plz help me in correcting my error…
