MatOrderingType
String with the name of a PETSc matrix ordering
Synopsis
typedef const char* MatOrderingType;
#define MATORDERINGNATURAL "natural"
#define MATORDERINGND "nd"
#define MATORDERING1WD "1wd"
#define MATORDERINGRCM "rcm"
#define MATORDERINGQMD "qmd"
#define MATORDERINGROWLENGTH "rowlength"
#define MATORDERINGWBM "wbm"
#define MATORDERINGSPECTRAL "spectral"
#define MATORDERINGAMD "amd" /* only works if UMFPACK is installed with PETSc */
#define MATORDERINGNATURAL_OR_ND "natural_or_nd" /* special coase used for Cholesky and ICC, allows ND when AIJ matrix is used but Natural when SBAIJ is used */
#define MATORDERINGEXTERNAL "external" /* uses an ordering type internal to the factorization package */
Notes
If MATORDERINGEXTERNAL is used then PETSc does not compute an ordering and utilizes one built into the factorization package
