Detailed Description

4x4 Matrix structure for 3D transformations and projections.

Provides basic matrix operations and utilities for 3D graphics, including identity, multiplication, translation, scaling, rotation (Z axis), view (LookAt), and perspective projection matrices.

Data is stored in a 16-element float array in column-major order.
