Function documentation

Cartesian2D & operator=(const ROOT::Math::Cartesian2D<double>& v)
assignment operator
void SetCoordinates(ROOT::Math::Cartesian2D<double>::Scalar x, ROOT::Math::Cartesian2D<double>::Scalar y)
Set internal data based on 2 Scalar numbers
{ fX=x; fY=y; }
void GetCoordinates(ROOT::Math::Cartesian2D<double>::Scalar& x, ROOT::Math::Cartesian2D<double>::Scalar& y) const
get internal data into 2 Scalar numbers
{x=fX; y=fY; }
Scalar X()
{ return fX;}
Scalar Y()
{ return fY;}
Scalar Mag2()
{ return fX*fX + fY*fY; }
Scalar R()
{ return std::sqrt( Mag2());}
Scalar Phi()
{ return (fX==0 && fY==0) ? 0.0 : atan2(fY,fX);}
void SetX(ROOT::Math::Cartesian2D<double>::Scalar x)
set the x coordinate value keeping y constant
{ fX = x; }
void SetY(ROOT::Math::Cartesian2D<double>::Scalar y)
set the y coordinate value keeping x constant
{ fY = y; }
void SetXY(ROOT::Math::Cartesian2D<double>::Scalar x, ROOT::Math::Cartesian2D<double>::Scalar y)
 all values using cartesian coordina
void Scale(ROOT::Math::Cartesian2D<double>::Scalar a)
scale the vector by a scalar quantity a
{ fX *= a; fY *= a; }
void Negate()
negate the vector
{ fX = -fX; fY = -fY; }
void Rotate(ROOT::Math::Cartesian2D<double>::Scalar angle)
rotate by an angle
Scalar x()
 ============= Compatibility section ==================
 The following make this coordinate system look enough like a CLHEP
 vector that an assignment member template can work with either
{ return X();}
Scalar y()
{ return Y();}
void SetR(ROOT::Math::Cartesian2D<double>::Scalar r)
 ====== Set member functions for coordinates in other systems =======
void SetPhi(ROOT::Math::Cartesian2D<double>::Scalar phi)
