Detailed Description

Simple rotation matrix implementation used to reorient Particle objects based on the incident neutrino direction.

Constructor & Destructor Documentation

RotationMatrix()

marley::RotationMatrix::RotationMatrix	(	const ThreeVector &	from_vec,
		const ThreeVector &	to_vec
	)

Create a 3×3 rotation matrix that rotates the 3-vector from_vec into the 3-vector to_vec.

This function is a C++11 version of an original rotation matrix program by Möller & Hughes (see this GitHub page for details)

The vectors from_vec and to_vec do not need to be normalized, but both should be nonzero. If either vector is a null vector, then a marley::Error will be thrown.
