Not sure if I am doing something wrong, but RunLength looks for RunLength.c which is not there.

Ok = InstallMex('RunLength.c', 'uTest_RunLength');

RLE worked perfectly:

RunLength.c is definitely included in the download zip

@hamed: Click on the "Download" button on the top right to obtain the zip file, which contains the required C file. You need a C compiler to convert the C file to a mex function. Alternatively you can use the slower RunLength_M version.
