Re: st: RE: matsum - matrix sums of rows
Thank you very much indeed. My problem was precisely identifying the
name of the matrix with the results. All fine now.
Le 24 ao�t 06 � 15:14, Nick Cox a �crit :
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 row-wise, column-wise and over-all
maximum,
minimum, and sum over the elements of a matrix. More than one
operator may
be specified simultaneously. These commands default to the
column-wise
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
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.
