How to get MATLAB to reload its cached internal m-files

I need to change the publish.m file ([matlabroot]/toolbox/matlab/codetools/publish.m) to make the font size of published equations somewhat bigger. I used to do it in previous versions of MATLAB and it worked successfully, but in 2015a it seems that the change isn't noticed.

I've tried restarting MATLAB or running clear publish to no avail.

Do you know how I can make MATLAB recognize the change?

It's a bit of a tedious method, but it works. Basically, you run MATLAB as administrator, navigate to .../toolbox/matlab/codetools/, edit the publish.m file, and then run

pcode publish.m

This will regenerate the publish.p in that folder (it must exist, and MATLAB only reads that file). Just note that if you also have a non-admin instance of MATLAB open at the same time that you're using for publishing, you should run

 clear all

or at least

 clear publish

every time you make edits to the .m file and regenerate the .p file (MATLAB will cache the version of the .p file that existed when you opened that instance, unless you force-clear it).

Edit (10/11/15): Based on the comment below by Walter Roberson, and which I have confirmed on Windows, it is sufficient to run

    rehash toolboxcache

after making changes.

In OS-X I see no indication that MATLAB has a publish.p -- it appears to be relying upon the .m file.

rehash toolboxcache

Thanks, it worked! and it was not at all tedious :)

@Walter Roberson your method does indeed work on Windows. Editing my answer.
