dgssrp - Return permutation used by the general sparse solver.
SUBROUTINE DGSSRP ( PERM, HANDLE, IER )
INTEGER PERM(*), IER DOUBLE PRECISION HANDLE(150)
DGSSRP - Returns the permutation used by the solver for the fill-reducing ordering.
PERM(NEQNS)
- INTEGER arrayPERM(NEQNS)
is the permutation array
used by the sparse solver for the fill-reducing ordering.
Modified on exit.
HANDLE(150)
- DOUBLE PRECISION arrayHANDLE(*)
is an array containing information
needed by the solver, and must be passed unchanged to each
sparse solver subroutine.
Modified on exit.
