SetColumn(int, Vector4)

Sets a column of the matrix.
public void SetColumn(int index, Vector4 column)

Parameters

index

int

column

Vector4

Remarks

You use this to build transformation matrices using right, up and forward vectors:
using UnityEngine;public class ExampleScript : MonoBehaviour{    // build a matrix from a transform.    Matrix4x4 matrix = new Matrix4x4();    /// Build a matrix from a transform.    void Start()    {        matrix.SetColumn(0, transform.right);        matrix.SetColumn(1, transform.up);        matrix.SetColumn(2, transform.forward);        var p = transform.position;        matrix.SetColumn(3, new Vector4(p.x, p.y, p.z, 1));    }}
The i-th column is set from 
v
. 
i
must be from 0 to 3 inclusive.
