2.2.2

• Transpose and multiply now work properly for non-square matrices.

2.2.1

• Fix calculation of inverted matrices with an even number of rows or columns (2x2, 4x4 etc).
• Use a simpler and faster algorithm for 2x2 matrices when calculating the inverse.

2.2.0

• Add Matrix#copy() to cheaply copy the data from another matrix.
• Add Matrix#isIdentity() to test if the data in the matrix represents the identity matrix.
• Optimize code for scenarios where a lot of matrix operations happen often (animation loops etc). The code will now try to create new internal objects/arrays as rarely as possible for the calculations.

2.1.0

• Add Matrix#toLogString() for easy logging output for debugging.

2.0.1

Improve performance by caching internal matrix instances created by the methods invert and getDeterminant.

2.0.0

Updated the Matrix class API to be nicer to the memory footprint.

1.0.0

Initial release.
