I try to use the package, but it did not work.
matlab msg:
Corrupt P-file "D:\matlab\run-length matrix\Mymatlab\grayrlmatrix.p".

Error in ==> test at 6
GLRLMS = GRAYRLMATRIX(m,'Offset',1,'NumLevels',8,'G',[]);

Please update the package with running grayrlmatrix.p file

Interesting code !
I was looking for statistics on run length and it's a good starting point.
But you don't mention Stefan Eireiner and use its code even if there are other ways to compute run length which are best for the memory than cell arrays.

Bug fixed version
It issued wrong outputs when handling nonsquare matrix. Now We output cell matrix instead of multi-dimensional matrix.
