zgssrp - Return permutation used by the general sparse
solver.
SUBROUTINE ZGSSRP ( PERM, HANDLE, IER )
INTEGER PERM(*), IER
DOUBLE PRECISION HANDLE(150)
ZGSSRP - Returns the permutation used by the solver for the
fill-reducing ordering.
PERM(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 numbers set by this subroutine:
-600 : Invalid calling sequence - need to call ZGSSOR first.
