setcol

Sets a given column of a 2-dimensional array from a vector.

The output is an 2-d array with the contents of the requested column set to values of the input array (1-d; if 2-d the first row of the input array is used).

Syntax

i/kout[] setcol i/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.

kin[] -- input array.

kcol -- column to be set.

Examples

Here is an example of the setcol opcode. It uses the file setcol.csd.
