Help Matlab understand where a (to-be-folded) code section begins and ends

Hello,

I would like certain sections (rows) in my Matlab script to be foldable as a section code (cell). These rows do not necessarily always have an "end" keyword terminating them, and so I'd like to define myself where a code section begins and ends.

However, it seems that Matlab only understands the beginnings (marked with %%), and not the endings, of such code sections. Matlab seems to look for various other clues (such as code keywords like 'case') as the end of a code section, and ignores % or %% symbols, which I inserted in order to tell Matlab this is where I'd like the cell to end.

Any help with this much appreciated!
