*DECK PIJXL3
SUBROUTINE PIJXL3(IPTRK,IPRT,NGRP,NANI,NBMIX,NPSYS,NRENOR,LEAKSW,
> XSSIGT,XSSIGW,NELPIJ,PIJ)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Calculation of the collision probabilities in EXCELL without producing
* a tracking file. Based on subroutine XL3TRK in DRAGON 3.4.
*
*Copyright:
* Copyright (C) 2005 Ecole Polytechnique de Montreal
* This library is free software; you can redistribute it and/or
* modify it under the terms of the GNU Lesser General Public
* License as published by the Free Software Foundation; either
* version 2.1 of the License, or (at your option) any later version
*
*Author(s): R. Roy and A. Hebert
*
*Parameters: input
* IPTRK pointer to the tracking (L_TRACK signature).
* IPRT print flag (equal to zero for no print).
* NGRP number of energy groups.
* NANI number of Legendre orders (usually equal to one).
* NBMIX number of mixtures.
* NPSYS index set to zero if a group is not to be processed. Usually,
* NPSYS(I)=I.
* NRENOR normalization scheme for PIJ matrices.
* LEAKSW leakage flag (=.true. if neutron leakage through external
* boundary is present).
* XSSIGT total macroscopic cross sections ordered by mixture.
* XSSIGW P0 within-group scattering macroscopic cross sections
* ordered by mixture.
* NELPIJ number of elements in symmetrized pij matrix.
*
*Parameters: output
* PIJ reduced and symmetrized collision probabilities.
