.m files are now interpreted as MATLAB in QuickLook

.m files are now interpreted as matlab instead of obj-c. the rest is the same as the original plugin from @mooflu.

for developers: download the zip file and that should be the only codebase necessary for all modification instead of working on two different folders.

if you just need the plugin you can instead download the .qlplugin and install it by pressing space on your windows explorer like any other QuickLook plugin.
