Dear Nick,

Thanks a lot. I converted a lower-triangular matrix from stata to mata form to apply the mata makesymmetric command but it doesn't work.
The command is 

: makesymmetric(mat_S2)
[symmetric]
       1   2
    +---------+
  1 |  0      |
  2 |  1   0  |
    +---------+

Would you have any suggestion?
Best,
Bianca



. mat foo = J(6,7,42)

. mat li foo

foo[6,7]
    c1  c2  c3  c4  c5  c6  c7
r1  42  42  42  42  42  42  42
