Matrix4 represents a double precision 4x4 matrix and contains a flag, set at object creation, indicating if the given Matrix4 object is mutable. Note: some algorithms in this class were ported from Eberly, Wolfram, Game Gems and others to Java.
com.badlogic.gdx.math.Matrix4
kipedia.org/wiki/Row-major_order#Column-major_order">column major 4 by 4 matrix. Like the {@link Vector3} class it allows the chaining of methods by returning a reference to itself. For example:
```
 Matrix4 mat = new Matrix4().trn(position).mul(camera.combined); 
```

org.apache.sis.referencing.operation.matrix.Matrix4

A matrix of fixed {@value #SIZE}× {@value #SIZE} size, often used in datum shifts.The matrix members are:

 ┌                 ┐ │  {@linkplain #m00} {@linkplain #m01} {@linkplain #m02} {@linkplain #m03} ││  {@linkplain #m10} {@linkplain #m11} {@linkplain #m12} {@linkplain #m13} ││  {@linkplain #m20} {@linkplain #m21} {@linkplain #m22} {@linkplain #m23} ││  {@linkplain #m30} {@linkplain #m31} {@linkplain #m32} {@linkplain #m33} │└                 ┘
