I would also test save('myFile.mat','C','-v6') - on my system it's faster than the naive for loop, almost as fast as your RLE solution, and much simpler and easier to develop, debug and maintain.

p.s. - using '-v7' results in a smaller file but takes a bit longer to perform. Depending on your I/O speed (e.g., whether you're using SSD) it could also be worth checking.
