Using GUI GUIDE what is the code to get an output from a equation/code that is in the GUI code, which is assigned to a variable, to display in a static text box.
More info: I have a GUI that grabs a set of data from an excel file with two columns and assigns one column to X and another to Y and then runs this through the Simpson 1/3 function in MATLAB and assigns that value to C. How do i get the variable C to display in the static Text box?

textLabel = sprintf('Variable C = %f', C);
set(handles.text1, 'String', textLabel);

If you are defining a function, then
function DisplayThem(handles, A,B,C,D)
text11 = sprintf('%0.4f', A);
set(handles.text1,'String',text11);
text12 = sprintf('%0.4f', B);
set(handles.text2,'String',text12);
text13 = sprintf('%0.4f', C);
set(handles.text3,'String',text13);
text14 = sprintf('%f', D);
set(handles.text4,'String',text14);
But perhaps your line
[RN1,RN2,RN3,RN4] = function(A,B,C,D);
was just an unfortunate use of the reserved word "function" and should have been some function name. If so then that code would be okay provided that handles.text1 and so on had already been created as uicontrol('style','text')
