MATLAB: Modification of built-in dialog boxes

Question

As an experiment, I made some modifications to the built in error dialog box function (by typing edit errordlg ) and saved it under the same name. If I then call the errordlg function from a script, my changes appear as the were intended. However, if I compile the script and run it as an executable, the default appearance of the dialog box is restored. Out of curiosity, why is this so?

It's using the one built-into and embedded in the MCR installer, not the one you modified. If you put the file into the same folder as your main executable, then I think it should use that in preference to the default one, both in your MATLAB and your target user who is using MCR.
