public float determinant;


The determinant of the matrix. (Read Only)

You can not invert matrices with a determinant of zero.

using UnityEngine;

public class ExampleScript : MonoBehaviour { void Update() { // create a transformation matrix with scale, zero position and no rotation var scale = new Vector3(5,3,2); var matrix = Matrix4x4.TRS(, Quaternion.identity, scale);

// determinant of a scaled matrix is volume of the parallelepiped // formed from its axes, in this case 5*3*2=30 Debug.Log(matrix.determinant); } }

See Determinant on Wikipedia for more details.
