SLATEC Routines --- DSLI ---

*DECK DSLI
      SUBROUTINE DSLI (N, B, X, NELT, IA, JA, A, ISYM, RWORK, IWORK)
C***BEGIN PROLOGUE  DSLI
C***PURPOSE  SLAP MSOLVE for Lower Triangle Matrix.
C            This routine acts as an interface between the SLAP generic
C            MSOLVE calling convention and the routine that actually
C                      -1
C            computes L  B = X.

C***DESCRIPTION
C       It is assumed that RWORK and IWORK have initialized with
C       the information required for DSLI2:
C          IWORK(1) = NEL
C          IWORK(2) = Starting location of IEL in IWORK.
C          IWORK(3) = Starting location of JEL in IWORK.
C          IWORK(4) = Starting location of EL in RWORK.
C       See the DESCRIPTION of DSLI2 for details.
