List of all members.

Detailed Description

A vector in a 2D space.

Notation of values and constructor order arguments are column based:

        x
        y

Public Member Functions
	Vector ()
	Constructor, create vector with coordinates (0, 0).
	Vector (double v)
	Constructor, create vector with coordinates (v, v).
	Vector (double x, double y)
	Constructor, create vector with coordinates (x, y).
	Vector (double array[2])
	Constructor, create vector with coordinates (array[0], array[1]).
void	operator+= (const Vector &v)
	Add vector v component by component.
void	operator-= (const Vector &v)
	Substract vector v component by component.
void	operator *= (double f)
	Multiply each component by scalar f.
void	operator/= (double f)
	Divive each component by scalar f.
Vector	operator+ (const Vector &v) const
	Add vector v component by component and return the resulting vector.
Vector	operator- (const Vector &v) const
	Substract vector v component by component and return the resulting vector.
Vector	operator/ (double f) const
	Multiply each component by scalar f and return the resulting vector.
Vector	operator * (double f) const
	Divive each component by scalar f and return the resulting vector.
double	operator * (const Vector &v) const
	Return the scalar product with vector v.
double	norm (void) const
	Return the norm of this vector.
double	norm2 (void) const
	Return the square norm of this vector (and thus avoid a square root).
double	cross (const Vector &v) const
	Return the cross product with vector v.
Vector	unitary (void) const
	Return a unitary vector of same direction.
double	angle (void) const
	Return the angle with the horizontal (arc tangant (y/x)).
