Kinematic tools are defined in [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Common/Kinematics/Kinematics| Common/Kinematics] package. SCT kinematics classes are based on <code>Eigen3</code> library. ROOT implementation of vectors and matrices is abandoned intentionally as too slow.

== ThreeVector ==
[https://git.inp.nsk.su/sctau/aurora/-/blob/master/Common/Kinematics/Kinematics/ThreeVector.h | ThreeVector.h] (contributors: D. Yakovlev, V. Vorobyev)

The ThreeVector class inherits from <code>Eigen::Matrix<ftype, 1, 3></code>

<code>
template <typename ftype = double>
class ThreeVector : public Eigen::Matrix<ftype, 1, 3>
</code>

ThreeVector can be initialized in Cartesian or polar coordinates:

<code>
ThreeVector v1(x, y, z);
ThreeVector v2 = ThreeVector::fromRPhiCosth(r, phi, costh)
</code>
