Symbolic cumulative sum
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. The
output B
has the same size as A
.
If A
is a vector, then cumsum(A)
returns a vector containing the cumulative sum of the elements of
A
.
If A
is a matrix, then cumsum(A)
returns a matrix containing the cumulative sums of each column of
A
.
If A
is a multidimensional array, then
cumsum(A)
acts along the first
nonsingleton dimension.
