4.4 Optical Elements and related numerical procedures 103b§g§§4§ g4MATPROD: Matrix transferMATPROD performs a matrix transfer of the particle coordinates in the following way4 f g4jb af1 bigbigkjg d joptics [15]. Second order transfer is optional. The length of the element represented by the matrix may be introducedwhere, §stands for any of the current coordinates , , , ¥ , path length and dispersion, and §bstands for any of theinitial coordinates. ?1 big A (?bhgkj A) is the first order (second order) transfer matrix as usually involved in second order beamfor the purpose of path length updating. Note : MATRIX delivers ?straightforward use with MATPROD.1 big Aand ?bigkj Amatrices in a format suitable for
