Its data stores 4-value array of column-major matrix elements. You can use cyMatrix2f with cyPoint2f to transform 2D points. Both post-multiplication and pre-multiplication are supported. Public Member Functions Constructors   cyMatrix2f ()   Default constructor.   cyMatrix2f (const cyMatrix2f &matrix)   Copy constructor.
