22/** \file H_TransportMatrices.h
23 * \brief Contains the matrices defining the propagation of the beam.
24 *
25 * The matrices should have the following units :
26 * \f$
27 * \mathbf{M} =
28 * \left(
29 * \begin{array}{cccccc}
30 * 1 & 1/m & 1 & 1/m & GeV/m & 1 \\
31 * m & 1 & m & 1 & GeV & 1 \\
32 * 1 & 1/m & 1 & 1/m & GeV/m & 1\\
33 * m & 1 & m & 1 & GeV & 1 \\
34 * m/GeV & 1/GeV & m/GeV & 1/GeV & 1 & 1\\
35 * 1 & 1 & 1 & 1 & 1 & 1 \\
36 * \end{array}
37 * \right)
38 * \f$
39 *
40 * Note : convention is transposed compared to ref : x0.M = x1
41 * instead of x1 = M.x0 so the matrices should be transposed.
