subscript question

  • To: mathgroup at smc.vnet.net
  • Subject: [mg71831] subscript question
  • From: "dimitris" <dimmechan at yahoo.com>

mat = Table[Subscript[x, i, j], {i, 1, 3}, {j, 1, 3}];

Something like

Apply[Plus, mat, 1]

works fine.

However

Tr[mat]

returns back the command.

Why?

Thanks

Dimitris
