A third alternative to your search is to look at the program
itself. It is just more Stata.
After your command you have a new matrix r in memory,
so its elements are
r[1,1], r[2,1], ....
In the help,
matsum A [, row(mat_name) column(mat_name) all(mat_name) display format(fmt)]
Computes and/or displays the rowwise, columnwise and overall maximum,
minimum, and sum over the elements of a matrix. More than one operator may
be specified simultaneously. These commands default to the columnwise
operators.
the implication is that you are naming a new matrix with whatever you
supply as mat_name.

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 rowwise 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.* * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
