with
h=histogram(sum(A,2),[0:5])
count=h.Values
0 0 2 1 1
you have the result in the variable count, reading:
0 rows have null '1', 0 rows have one '1', 2 rows have two '1', 1 row has three '1' and 1 row has four '1'.
the histogram field to the right, filled with [0:5] defines the histogram bin edges: 4 bins need 5 edges.
