cumprod

Syntax

R = cumprod(x)

R = cumprod(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 product.

Examples

Along default dimension:

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

ans = [Matrix] 2 x 3
1   2   3
4  10  18

Using row dimension:

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

ans = [Matrix] 2 x 3
1   2    6
4  20  120

Comments

Returns the cumulative product starting at the beginning of the first array.
