ISSetIdentity#

Informs the index set that it is an identity.

Synopsis#

#include "petscis.h" 
PetscErrorCode ISSetIdentity(IS is)

Logically Collective

Input Parameter#

  • is - the index set

Note: The IS will be considered the identity permanently, even if indices have been changes (for example, with ISGeneralSetIndices()). It’s a good idea to only set this property if the IS will not change in the future. To clear this property, use ISClearInfoCache().
