The output is an 1-d array with the contents of the requested column

Syntax

i/kout[] getcol i/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.

kcol -- column to be extracted.
