A standard 4x4 transformation matrix.
A transformation matrix can perform arbitrary linear 3D transformations (i.e. translation, rotation, scale, shear etc.)
and perspective transformations using homogenous coordinates. You rarely use matrices in scripts; most
often using Vector3s, Quaternions and functionality of Transform class is more straightforward. Plain matrices are used in special cases
like setting up nonstandard camera projection.
Consult any graphics textbook for in depth explanation of transformation matrices.
In Unity, Matrix4x4 is used by several Transform, Camera, Material and GL functions.
Matrices in unity are column major. Data is accessed as: row + (column*4). Matrices can be
indexed like 2D arrays but in an expression like mat[a, b], a refers to the row index, while b refers
to the column index (note that this is the opposite way round to Cartesian coordinates).
