atpass   

ATPASS is a numerical tracking engine for AT 1.3
 ROUT = ATPASS(LATTICE,RIN,MODE,NTURNS,REFPTS)

   LATTICE     AT lattice
   RIN         6xN matrix: input coordinates of N particles
   MODE        0 - reuse lattice
               1 - new lattice
   NTURNS      number of turns
   REFPTS      Indexes of elements where the trajectory is observed
               May run from 1 to length(LATTICE)+1

 ROUT = ATPASS(LATTICE,RIN,MODE,NTURNS,REFPTS,PREFUNC,POSTFUNC)
   PREFUNC     function called before each element
   POSTFUNC    function called after each element

 [ROUT,LOST] = ATPASS(LATTICE,RIN,MODE,NTURNS,REFPTS,PREFUNC,POSTFUNC,NHIST)
   Returns additionally information on lost particles

   NHIST       length of history buffer
   LOST        1x1 structure with the following fields:
               turn        1xN vector, turn number where the particle is lost
               element     1xN vector, element number where the particle is lost
               coordinates 6xNxNHIST matrix, coordinates at the entrance of the
                           element where the particle was lost
