11The MATRIX permits the definition of an arbitrary transfer matrix.
12It has four real array attributes:
13<ul>
14<li>L:
15Length of the element, which may be zero.
16<li>KICKi:
17Defines the kick of the element acting on the six phase space coordinates.
18</li><li>RMik:
19Defines the linear transfer matrix (6*6) of the element.
20</li><li>TMikl:
21Defines the second-order terms (6*6*6) of the element.
22</li></ul>
23Data values not entered are taken from the identity transformation,
24kick and second order terms are zero as default. In the thin-lens
25tracking module the length of an arbitrary matrix is accepted, however
26no second order are allowed to avoid non symplectic tracking runs. In
27the latter case the tracking run will be aborted.
