MATLAB: How to use string within a line of code

guihandlesstr2func

I was trying to use a string as a object handle within a for loop to save space as following:
function pushbutton1_Callback(hObject, eventdata, handles)
for Button = 1
Button = num2str(Button);
Obj = strcat('handles.Num',Button);
set(str2func(Obj), 'ForegroundColor','red')
set(handles.Num1, 'ForegroundColor','red')
end
I would like to use Obj to replace handles.Num1. is there any way to do this?

Best Answer

handles.( [ 'Num', num2str( button ) ] )
should work, although quite what you are doing with Button I can't work out
for Button = 1
is pointless and
Button = num2str(Button);
overwriting the loop variable is also not good code.
