You can use this:

m = randi(9, 3, 3)
sums = sum(m, 2) % Get row sums (sum across columns within rows)
minSum = min(sums);  % Find min sum value - may occur more than once.
rowsWithMinSum = find(sums == minSum)

For example, you might see this in the command window:

m =
     1     8     2
     4     4     3
     3     9     2
sums =
    11
    11
    14
rowsWithMinSum =
     1
     2

You need to do it like this rather than use the min function's second output because that will only find the first min, and if the min occurs more than once, it won't find the rest.

[~,r] = min(sum(A,2))
