cumsum
Cumulative sum
Description
returns
the cumulative sum of B
= cumsum(A
)A
starting at the beginning
of the first array dimension in A
whose size does
not equal 1.
If
A
is a vector, thencumsum(A)
returns a vector containing the cumulative sum of the elements ofA
.If
A
is a matrix, thencumsum(A)
returns a matrix containing the cumulative sums for each column ofA
.If
A
is a multidimensional array, thencumsum(A)
acts along the first nonsingleton dimension.
