## Syntax

    i/kout[] setcoli/kin[],i/kcol

## Initialization

iout[] -- output array containing the extracted column. It will be created if it does not exist.

iin[] -- input array.

icol -- column to be extracted.

## Performance

kout[] -- output array containing the set column. It will be created if it does not exist.
