This script is useless. 
diag(diag(m)) does the same job, and much faster i guess (diag() is a built-in):

--> m = grand(5,5,"uin",0,9)
 m  = 
   3.   9.   6.   1.   0.
   2.   4.   2.   9.   1.
   3.   4.   1.   8.   8.
   0.   5.   0.   5.   1.
   9.   7.   4.   2.   7.


--> diag(diag(m))
 ans  =
   3.   0.   0.   0.   0.
   0.   4.   0.   0.   0.
   0.   0.   1.   0.   0.
   0.   0.   0.   5.   0.
   0.   0.   0.   0.   7.
