ISSetLayout#

set PetscLayout describing index set layout

Synopsis#

#include "petscis.h" 
PetscErrorCode ISSetLayout(IS is, PetscLayout map)

Collective

Input Parameters#

  • is - the index set

  • map - the layout

Notes#

Users should typically use higher level functions such as ISCreateGeneral().

This function can be useful in some special cases of constructing a new IS, e.g. after ISCreate() and before ISLoad(). Otherwise, it is only valid to replace the layout with a layout known to be equivalent.
