st: sum of rows in matrix
Appologies if this is a very basic question, but a lengthy search of the archives didn't answer my query.
How can I create a vector, where each element is the sum of each row in a matrix A?
mat list A
A[2,5] c1 c2 c3 c4 c5 r1 1 2 3 4 5 r2 6 7 8 9 10
I would like to create B where:
B[2,1] c1 r1 15 r2 40
Thanks in advance,
