SCOTCH stratMeshOrder
Synopsis
int SCOTCH stratMeshOrder (SCOTCH Strat *
straptr,
const char *
string)
scotchfstratmeshorder (doubleprecision (*)
stradat,
character (*)
string,
integer
ierr)
Description
The
SCOTCH stratMeshOrder
routine fills the strategy structure pointed to by
straptr
with the mesh ordering strategy string pointed to by
string
. From
this point, strategy
strat
can only be used as a mesh ordering strategy, to
be used by function
SCOTCH meshOrder
, for instance.
When using the C interface, the array of characters pointed to by
string
must be null-terminated.
Return values
SCOTCH stratMeshOrder
returns 0 if the strategy string has been successfully
set, and 1 else.

SCOTCH stratMeshOrderBuild
Synopsis
int SCOTCH stratMeshOrderBuild (SCOTCH Strat *
straptr,
const SCOTCH Num
flagval,
const double
balrat)
scotchfstratmeshorderbuild (doubleprecision (*)
stradat,
integer*
num
flagval,
doubleprecision
balrat,
integer
ierr)
Description
The
SCOTCH stratMeshOrderBuild
routine fills the strategy structure pointed
to by
straptr
with a default ordering strategy tuned according to the prefer-
ence flags passed as
flagval
and to the desired nested dissection imbalance
ratio
balrat
. From this point, the strategy structure can only be used as
an ordering strategy, to be used by function
SCOTCH meshOrder
, for instance.
See Section 7.3.1 for a description of the available flags.
Return values
SCOTCH stratMesdOrderBuild
returns 0 if the strategy string has been suc-
cessfully set, and 1 else.
