Method Description
Mat33 ( System.Vector3 c1, System.Vector3 c2, System.Vector3 c3 ) : System

Construct this matrix using columns.
SetZero ( ) : void

Set this matrix to all zeros.
Solve22 ( System.Vector2 b ) : System.Vector2

Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases. Solve only the upper 2-by-2 matrix equation.
Solve33 ( System.Vector3 b ) : System.Vector3

Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.
