The Matrix class specifies transformation from one coordinate space to another.
These transformations include translation, rotation, scaling and skewing.
A 2D transformation matrix is a 3 x 3 matrix in homogenous coordinate system:

You can get and set the values of all six of the properties in a
Matrix object: m11, m12, m21, m22, tx, and ty.
Since Gideros 2016.6, Matrix can also hold 3D (4x4) matrices.

Common uses and examples:

Applying matrix to Sprite objects

local angle = math.rad(30)
-- create skew matrix
local m =, math.tan(angle), math.tan(angle), 1, 0, 0)
--aply to Sprite
local sprite =
