Matlab highlighting inconsistencies: after the transpose .' the text becomes a string
As written from Ryan Ollos here: https://bitbucket.org/birkenfeld/pygments-main/issue/414/matlab-lexer-doesnt-properly-handle when the operator transpose .' occurs, all the text until the next ' is treated as if it was a string.
You can see this behaviour on this: https://github.com/alexpacini/Uni.Snippets/blob/master/TIC/assignment04_noisyap2LHamm/decHD.m
The GitHub support explicitly said (today) they use pygments for the highlighting and so to file the bug here.
