Description
TMatrix is an array of vectors in a two-dimensional space. It is used for vector transformations in 2D-space.
TMatrix is a record that represents three vectors, each in a two-dimensional space. The vectors have their initial points in (0, 0). m11 and m12 are the coordinates of the terminal point of the first vector (similar for the other two). The TMatrix is used for vector transformations in 2D-space.
