>> help menu
 menu   Generate a menu of choices for user input.
    CHOICE = menu(HEADER, ITEM1, ITEM2, ... ) displays the HEADER
    string followed in sequence by the menu-item strings: ITEM1, ITEM2,
    ... ITEMn. Returns the number of the selected menu-item as CHOICE,
    a scalar value. There is no limit to the number of menu items.
 
    CHOICE = menu(HEADER, ITEMLIST) where ITEMLIST is a string, cell
    array is also a valid syntax.
 
    On most graphics terminals menu will display the menu-items as push
    buttons in a figure window, otherwise they will be given as a numbered
    list in the command window (see example, below).
 
    Example:
        K = menu('Choose a color','Red','Blue','Green')
        %creates a figure with buttons labeled 'Red', 'Blue' and 'Green'
        %The button clicked by the user is returned as K (i.e. K = 2 
        implies that the user selected Blue).
