The -x- bit is used to make an file executable (the fact that there are 
three -x-'s is for the user/group/all)
So unless you are using octave for some extremely exotic work (In which 
case I would recommend using something else) I cannot see the reason why 
you would want to execute your data-files from linux directly.
If you really want to give all permissions to the file you could do 
system('chmod 777 <filename>');
where <filename> is the filename you want to change. But please think 
again for using an other system to create executables.
