Class Mat4

src/main/java/field/linalg/Mat4.java:45–5719

Contains the definition of a 4x4 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 m30 m01 m11 m21 m31 m02 m12 m22 m32 m03 m13 m23 m33 @author Richard Greenlee
