Write a Matlab function that takes one input -- an MxN matrix -- and returns one output -- the row number of the matrix with the smallest row sum.

How do I rewirte this function without a for loop?

function min_row = min_row_sum(A)
min_row = 1;
min_total = 0;
[r, c] = size(A);
    for i=1:r
        total = 0;
        for j=1:c
            total = total+A(i, j);
        end
        if i==1 || total < min_total
            min_row = i;
            min_total = total;
        end
    end
end
