That should give you an example of what you want with the following function defined based on Guillame's input above :
function hexStr = rgb2Hex( rgbColour )
hexStr = reshape( dec2hex( rgbColour, 2 )',1, 6);
Obviously if you have a pre-existing listbox from Guide you can just do the usual:
set( handles.listbox1, 'String', listboxStr )
instead of creating a new listbox.
