HTCondor's file transfer mechanism preserves the permissions of the 
files it moves.  So if the job creates a file with perm 0600, then when 
the file is transferred back to the submit node HTCondor will keep the 
permission the same at 0600.  Perhaps you could create m.matlog as a 
zero-length file with the permissions you want and add it to 
transfer_intput_files? Also, I have to admit, I am not sure what happens 
if you are submitting from Linux and running on Windows (is that what 
you are doing?), and I also do not know if there is an equal to Linux's 
umask on Windows...

There is the knob JOB_EXECDIR_PERMISSION, but I don't that that matters 
for you...

Sorry I couldn't help more
