=============================================== Matrix - class to represent planar transformations =============================================== Matrix is used to perform following transformations: x1 = x * a + y * b + e y1 = x * c + y * d + f Matrix() - generic constructor, creates a Matrix that makes no change to coordinates Matrix(Matrix) - copy constructor Matrix([a, b, c, d, e, f]) - creates a Matrix and assigns coordinates from the list of float numbers Matrix(a, b, c, d, e, f) - creates a Matrix and assigns coordinates from float numbers a, b, c, d, e, f (float) - Matrix parameters add - Matrix must be second operand, all parameters are added subtract - Matrix must be second operand, all parameters are subtracted multiply (with Matrix) - matrixes are multiplied multiply (with float number) - all parameters are scaled by the operand Assign - assigns new values to a Matrix, uses the same syntax as in constructors Add(Matrix m) - adds values of the Matrix m to current matrix Sub(Matrix m) - subtracts values of the Matrix m from current matrix Mul(float s) - mutiplies Matrix's parameters to s value Transform(Matrix m) - applies Matrix m transformation to the current Matrix
