# cumprodc¶

## Purpose¶

Computes the cumulative products of the columns of a matrix.

## Format¶

y = cumprodc(x)
Parameters

x (NxK matrix) –

Returns

y (NxK matrix) – containing the cumulative products of the columns of x.

## Examples¶

x = { 1 -3,
2  2,
3 -1 };

y = cumprodc(x);


Now if you view y, you will see:

    1.000 -3.000
y = 2.000 -6.000
6.000  6.000


## Remarks¶

This is based on the recursive series recsercp(). recsercp() could be called directly as follows:

recsercp(x, zeros(1, cols(x)));


to accomplish the same thing.
