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

John - have you writtin your GUI with GUIDE, App Designer, or programmatically? The solution may be similar for each: in the pushbutton callback, get the list of items in the first popup menu (you will need to access to the handle of this object). Using this same handle, get the index of the selected item. Given the index and list, you will be able to determine the initial units of the number (to convert). Repeat for the second popup menu so that you have the units to convert to.
