How to control GUI with external m-file

I created a GUI, named 'StartEngine', there is a button 'Run'(handles.pushbutton1) on the GUI.
Now, I opened the GUI and I want to make Background color of this button to be gray with a m-file.
It means how could I implement the following command out of StartEngine.m (corresponding to StartEnge.fig)
set(handles.pushbutton1, 'BackgroundColor', [0.5, 0.5, 0.5]);

figs = findall(0, 'type', 'figure');
get(figs, 'Name')
get(figs, 'Tag')

Sounds like a decent plan, except part 2 ;)
One difficulty you may experience is troubleshooting any of those components when something goes wrong. Let's say you have a variable named "V" in one of the xx.m files in the bottom row. V should always be a positive integer but you noticed it's value is NaN. You have no idea where that value is coming from. It could come from any of these possibilities:
- from StartEngine
- from xx.m #1
- from xx.m #2
- From within ExecuteRun.m
- from an interaction in ExecuteRun between StartEngine and xx.m #1
- from an interaction in ExecuteRun between StartEngine and xx.m #2
- from an interaction in ExecuteRun between xx.m #1 and xx.m #2 within
and lots of other possibilities. This organization often make reproducibility difficult or even impossible.
One way to deal with many input and output variable is to organize them into a structure. For example,
function [motion, position] = movingObject(action)
end
Where the ouputs & inputs contains many fields
motion.velocity
motion.acceleration
motion.previousPosition
motion.currentPosition
% etc...
Anyway, I'm sure you'll figure this stuff out soon.
