Class Mat3

src/main/java/field/linalg/Mat3.java:47–1815

Contains the definition of a 3x3 Matrix of doubles, and associated functions to transform it. The matrix is column-major to match OpenGL's interpretation, and it looks like this: m00 m10 m20 m01 m11 m21 m02 m12 m22 @author Richard Greenlees @author Kai Burjack
