MATLAB: Does the menu item ‘Notebook’ not appear when I open Microsoft Word application with MATLAB 7.5 (R2007b)

MATLABnotebook

When I open an existing MATLAB Notebook document by using the following command, the menu item "Notebook" on the toolbar in Microsoft Word is missing:
notebook filename
However when I just open a blank MATLAB Notebook document using the following command, I do see the menu item "Notebook" on the toolbar:
notebook

Best Answer

When you open the file using the command below, the Menu item 'Notebook' will only appear if the file had been originally created using the Notebook application launched from the command line:
notebook filename
The best practice would be to create such a file using the command line.
For fixing the existing Microsoft Word files, you need to create a new file using the above command and Copy and Paste the data of the existing file into the new file.
