MATLAB: Bad Handle Error

gui simulink blocks-functionsimulation

Hi, what is bad handle error refer to? In an s-function code I always have to save the m-file to get it running again or this error confronting me. Any ideas?

What is the exact error message? Guessing from your description, it might mean that the S-function block is not able to execute the MATLAB-file for some reason. Perhaps you are running the model outside of the directory where the MATLAB-file is present? Have you added the file to the MATLAB path?

As its help clearly explains, run will run a script, but it will not run a function (e.g. a GUI main file).

PS: Avoid GUIDE. Writing your own code is better:

MATLAB: Handles.

It depends on how it was defined:

handles.num = 15

Now "handles" is a struct containing the field "num", which has the value 15. But if your define "handles" as object, it could be something different.

So please take the time to investigate it yourself:

class(handles)
whos('handles')
methods(handles)

If I dare to guess, "handles = guidata(FigureHandle)" might be the creator of the struct "handles". If so, see "help guidata" for more details.
