*DECK TRISPS
SUBROUTINE TRISPS(IPTRK,IPMACR,IPMACP,IPSYS,IMPX,NGRP,NEL,NLF,
1 NANI,NBFIS,NALBP,LDIFF,IPR,MAT,VOL,NBMIX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Recover the cross-section data in LCM object with pointer IPMACR,
* compute and store the corresponding Trivac system matrices for a
* simplified PN approximation (or a perturbation to the system
* matrices).
*

*
*Author(s): A. Hebert
*
*Parameters: input
* IPTRK L_TRACK pointer to the TRIVAC tracking information.
* IPMACR L_MACROLIB pointer to the unperturbed cross sections.
* IPMACP L_MACROLIB pointer to the perturbed cross sections if
* IPR.gt.0. Equal to IPMACR if IPR=0.
* IPSYS L_SYSTEM pointer to system matrices.
* IMPX print parameter (equal to zero for no print).
* NGRP number of energy groups.
* NEL total number of finite elements.
* NLF number of Legendre orders for the flux (even number).
* NANI number of Legendre orders for the scattering cross sections.
* NBFIS number of fissionable isotopes.
* NALBP number of physical albedos per energy group.
* LDIFF flag set to .true. to use 1/3D as 'NTOT1' cross sections.
* IPR type of assembly:
* =0: calculation of the system matrices;
* =1: calculation of the derivative of these matrices;
* =2: calculation of the first variation of these matrices;
* =3: identical to IPR=2, but these variation are added to
* unperturbed system matrices.
* MAT index-number of the mixture type assigned to each volume.
* VOL volumes.
* NBMIX total number of material mixtures in the macrolib.
