cumsum

Syntax

R = cumsum(x)

R = cumsum(x,dim)

Inputs

x

Any valid scalar | vector | matrix.

Type: double | integer | logical | struct | cell

Dimension: scalar | vector | matrix

dim

The dimension on which to accumulate.

Default: first non-singleton dimension.

Type: integer

Dimension: scalar

Outputs

R

The cumulative sum.

Examples

Using default dimension

cumsum([1,2,3;4,5,6])

ans = [Matrix] 2 x 3
1  2  3
5  7  9

Using row dimension

cumsum([1,2,3;4,5,6],2)

ans = [Matrix] 2 x 3
1  3   6
4  9  15
