I have a large script m-file (~188k lines) auto-generated by COMSOL Multiphysics (a finite element solver). 99.99% of those lines are oddly formatted COMSOL data (which I can't easily read in from a mat file).
I would be content to wrap these data sections in cell tags (%%) and fold them while I work, but it's not working.
I have cell mode turned on for the file and I've gone into preferences to make sure that code folding is enabled for cells.
I have inserted %% cell tags in the appropriate places, but they are not collapsible. (There's no minus sign next to them. In fact none of the code - if or for loops - is collapsible.) When I click on the "Show Cell Titles" button in the Editor toolbar, it says "No Cell Titles Found". If I use the"Insert Cell Break" toolbar button, the Editor cannot find a new cell.
Is is simply the size of the file that's breaking this feature, or am I missing something else?
