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

Initialization

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

iin[] -- input 2-dimensional array.

icol -- column to be extracted.

Performance

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

kin[] -- input 2-dimensional array.
