| Subject | st: how to summarize a big matrix |
| Date | Mon, 8 Apr 2013 13:40:38 -0700 (PDT) |
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!
