zgssrp(3P) Sun Performance Library zgssrp(3P)NAMEzgssrp - Return permutation used by the general sparse solver.
SYNOPSIS
SUBROUTINE ZGSSRP ( PERM, HANDLE, IER )
INTEGER PERM(*), IER
DOUBLE PRECISION HANDLE(150)PURPOSE
ZGSSRP - Returns the permutation used by the solver for the fill-reduc‐
ing ordering.
PARAMETERSPERM(NEQNS) - INTEGER array
Undefined on entry. PERM(NEQNS) is the permutation array used
by the sparse solver for the fill-reducing ordering. Modified
on exit.
HANDLE(150) - DOUBLE PRECISION array
On entry, HANDLE(*) is an array containing information needed
by the solver, and must be passed unchanged to each sparse
solver subroutine. Modified on exit.
IER - INTEGER
Error number. If no error encountered, unchanged on exit. If
error encountered, it is set to a non-zero integer. Error num‐
bers set by this subroutine:
-600 : Invalid calling sequence - need to call ZGSSOR first.
