GUI_31()
function [] = GUI_31()
% Demonstrate multiple uicontrol manipulations based on user choices.
% Creates a simple calculator which allows the user to make a choice of
% operations to use, as well as to enter numbers on which to operate.
% Notice that the static textbox will update to show which operation is
% current.
%
% Suggested exercise:  Add more operations to the popup, and have the code
% detect a rational answer (as best as you can with floating point, there 
% are many ways to do this, just pick some criteria).  If the answer is  
% not rational, change the '=' to '~' to mean, 'approximately equal to.'
