Matrix Package is a Java package for working with matrices. This package does most of what you would want a matrix package to do, but is optimsed to working with the 4x4 matrices used in 3D graphics.

The Matrix class provides a generalised 2-dimensional matrix package.

Matrices are treated as values wherever possible, so matrix operations such as multiplication produce a new matrix as the result, rather than operate directly on the matrix.

This package is optimised towards the 4x4 transformation matrices which can be used for 3D projections. There are a number of class methods for generating transformation matrices.
