TRotMatrix::TRotMatrix ( )

TRotMatrix::TRotMatrix	(	const char *	name,
		const char *	title,
		Double_t *	matrix

RotMatrix normal constructor.

TRotMatrix::TRotMatrix	(	const char *	name,
		const char *	title,
		Double_t	theta,
		Double_t	phi,
		Double_t	psi
	)

RotMatrix normal constructor.

TRotMatrix::TRotMatrix	(	const char *	name,
		const char *	title,
		Double_t	theta1,
		Double_t	phi1,
		Double_t	theta2,
		Double_t	phi2,
		Double_t	theta3,
		Double_t	phi3
	)

RotMatrix normal constructor defined a la GEANT.

The TRotMatrix constructor with six angles uses the GEANT convention:

theta1 is the polar angle of the x-prim axis in the main reference system (MRS), theta2 and theta3 have the same meaning for the y-prim and z-prim axis.

Phi1 is the azimuthal angle of the x-prim in the MRS and phi2 and phi3 have the same meaning for y-prim and z-prim.

for example, the unit matrix is defined in the following way.

x-prim || x, y-prim || y, z-prim || z
means:  theta1=90, theta2=90, theta3=0, phi1=0, phi2=90, phi3=0
