If you call a mex file from a non-standard location such as an external drive on SELinux, the following error is generated:

 ??? Invalid MEX-file '/media/sda3/.../timestwo.mexglx':
 /media/sda3/.../timestwo.mexglx: failed to map segment from shared
 object: Operation not permitted.

This issue is specific to bad device loading on SELinux.

As a workaround, copy the MEX file from the non standard location to a standard location such as a subdirectory in your home folder and try loading the MEX file from there.
