Detailed Description

A 2x2 matrix.

Notation of values and constructor order arguments are column based:

        a c
        b d

Public Member Functions
	Matrix22 ()
	Constructor, create matrix with 0.
	Matrix22 (double a, double b, double c, double d)
	Constructor, create matrix with a b c d.
	Matrix22 (double alpha)
	Constructor, create rotation matrix of angle alpha in radian.
	Matrix22 (double array[4])
	Constructor, create matrix with array[0] array[1] array[2] array[3].
void	operator+= (const Matrix22 &v)
	Add matrix v component by component.
void	operator-= (const Matrix22 &v)
	Substract matrix v component by component.
void	operator *= (double f)
	Multiply each component by scalar f.
void	operator/= (double f)
	Divive each component by scalar f.
Matrix22	operator+ (const Matrix22 &v) const
	Add matrix v component by component and return the resulting matrix.
Matrix22	operator- (const Matrix22 &v) const
