st: how to summarize a big matrix

Hi there,

   I am required to investigate the elements of a big matrix(1000X1000); what I am trying to do now is to VEC the matrix and change it into a variable, then use "sum" in stata. But that is very slow.

  I am just wondering whether there is an easier way to summarize the matrix directly? By the way, the matrix is symmetric.

Thank you very much!
