Class Matrix

Version added: before 9.5

The Matrix class is used to represent a 4x4 transformation matrix. Matrix objects are used to transform points in 3D space.

If necessary, instances of this class can be created by:

- Local variable:

local matrix = LM.Matrix:new_local()

- Global (see Script Structure about conventions for naming globals):

XX_matrix = LM.Matrix:new()
