'view' - example: "Error using uimenu"

Hello! I just startet working with Matlab. I took one example from the website, but an error occurred:

cm = [0 1 1 0 0;1 0 0 1 1;1 0 0 0 0;0 0 0 0 1;1 0 1 0 0]

bg = biograph(cm)

h = view(bg)

I get this error:

Error using uimenu
First argument must be a valid parent, such as a Figure or Panel object.

Error in biograph.bggui>makeBiographViewerUIMenus (line 298)
uimenu(hw,'Label','Export to Workspace...','Position',1,'Callback',{@exportToWorkspace,bh})

Error in biograph.bggui (line 38)
makeBiographViewerUIMenus(fh,bh);                    

Error in biograph.biograph/view (line 49)
    g = biograph.bggui(h);

What am I doing wrong, using the example?

Thank you!

If you precede these lines with close all,clear cm bg h, does that fix the error?

I can't really think of a reason why this would give an error, except if something strange is going on with previously defined variables or figure windows that have gotten special settings changed.

Hi Rik! Thank you! Now it works - I'm a total beginner. I was typing the code in mlx an not in m. I guess I should lern the difference. But it works :-)

Thank you!

I believe biograph needs to be updated to work properly in Live Scripts (MLX files). One workaround is to use a regular script (M file) instead.
