Displaying analytical results in the MATLAB GUI

Question

My problem is this: I have a MATLAB GUI, and I want to get analytic results if I run it to display in my GUI, and not in the command window. I tried using the list to display the results due to the sliders that are automatically created for the list, but this did not work. How can I display data, possibly using a static text field?

Answer 1

First, you will need to make sure that you suppress any output in the command window. You can do this by making sure that you end the lines with a semicolon , avoid using DISP to display data, and do not use the FPRINTF function to send data to standard output (i.e. the command window).

hList = uicontrol('Style','text','Position',[100 100 200 200]);
set(hList,'String',{'Line 1'; 'Line 2'});  % Displays 2 lines, one string each
vec = rand(3,1);  % Column array of 3 random values
set(hList,'String',num2str(vec));  % Displays 3 lines, one number per line
