Is this what you mean?

M = rand(5,6);
S = sum(cumsum(M),2);

[Muhammad Furqan]

M = rand(5,6); Mean that it creates random numbers of a matrix with 5 column and 6 rows. S = sum(cumsum(M),2); It generate commulative sum of the rows in one column. For example M = rand(2,3);

S = sum(cumsum(M),2); 1.02263280043603 2.03657698954441
