Hi to everyone !

I need your help guys, i'am a beeginer in Matlab and i have a problem with my project:

Well, i have to create a program that converts whatever number set to the measures: (Kilometers, meters, centimeters and millimeters).

On mi GUI i have 2 edit text and 2 popupmenu

The idea is:

I put one numer on the edittext1 and i choose in the popupmenu1 what measure it is(Kilometers, meters, centimeters and millimeters).

Then, on the other popupmenu i choose what measure in want to convert and that value has to print on the edittext 2. is like google conversor.

I don't know how to work with 2 popupmenus, i hope you guys help me.

Have a good day. :D

Try something like this

value = str2double(handles.edittext1.String)
if handles.popupmenu1.Value == 1
    if handles.popupmenu2.Value == 1
        convertedValue = value * 123.4567; % Or whatever it is.
    elseif handles.popupmenu2.Value == 2
    elseif handles.popupmenu2.Value == 3
    elseif handles.popupmenu2.Value == 4
    elseif handles.popupmenu2.Value == 5
    end
elseif handles.popupmenu1.Value == 2
    if handles.popupmenu2.Value == 1
    elseif handles.popupmenu2.Value == 2
    elseif handles.popupmenu2.Value == 3
    elseif handles.popupmenu2.Value == 4
    elseif handles.popupmenu2.Value == 5
    end
elseif handles.popupmenu1.Value == 3
    if handles.popupmenu2.Value == 1
    elseif handles.popupmenu2.Value == 2
    elseif handles.popupmenu2.Value == 3
    elseif handles.popupmenu2.Value == 4
    elseif handles.popupmenu2.Value == 5
    end
elseif handles.popupmenu1.Value == 3
    if handles.popupmenu2.Value == 1
    elseif handles.popupmenu2.Value == 2
    elseif handles.popupmenu2.Value == 3
    elseif handles.popupmenu2.Value == 4
    elseif handles.popupmenu2.Value == 5
    end
elseif handles.popupmenu1.Value == 5
    if handles.popupmenu2.Value == 1
    elseif handles.popupmenu2.Value == 2
    elseif handles.popupmenu2.Value == 3
    elseif handles.popupmenu2.Value == 4
    elseif handles.popupmenu2.Value == 5
    end
end
handles.edittext2.String = sprintf('In those units, the value is %f', convertedValue)

Inside each if block, do the conversion, or get the scaling factor, for the relevant pair that was chosen.
