st: matsum - matrix sums of rows

[Fabrizio Gilardi <Fabrizio.Gilardi@unil.ch>]

Dear Statalist,

I've been using the -matsum- command written by Jeroen Weesie. I  
would like to access the results (notably the sums of rows) to use  
them in further operations: how can I do this? I've perused the help  
and Statalist's archives, but I couldn't find a solution.

Example:

. matrix A=(1,2,3 \ 4,5,6)

. matrix list A

A[2,3]
    c1  c2  c3
r1   1   2   3
r2   4   5   6

. matsum A, r(r) d

row-wise sums of matrix A[2,3]

    c1
r1   6
r2  15


How can I access the sum of the first row of A (i.e. 6) and that of  
the second row of A  (i.e. 15)?

I'm still using Stata 7, but I should receive Stata 9 soon.

Thank you very much in advance,

Fabrizio Gilardi
