CUSUM Function |
The CUSUM function computes cumulative sums. The argument to this function is a numeric matrix or literal.
The CUSUM function returns a matrix of the same dimension as the argument matrix. The result contains the cumulative sums obtained by adding the nonmissing elements of the argument in row-major order.
For example, the following statements compute cumulative sums:
a = cusum({1 2 4 5}); b = cusum({5 6, 3 4}); print a, b;
