NAME

cgssrp - Return permutation used by the general sparse solver.

SYNOPSIS

 SUBROUTINE CGSSRP ( PERM, HANDLE, IER )

 INTEGER           PERM(*), IER
 DOUBLE PRECISION  HANDLE(150)

PURPOSE

CGSSRP - Returns the permutation used by the solver for the fill-reducing ordering.

PARAMETERS

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 CGSSOR first.
