PCGASMDestroySubdomains

Destroys the index sets created with PCGASMCreateLocalSubdomains() or PCGASMCreateSubdomains2D. Should be called after setting subdomains with PCGASMSetSubdomains().

#include "petscpc.h" 
PetscErrorCode  PCGASMDestroySubdomains(PetscInt n, IS iis[], IS ois[])

Collective

	n	- the number of index sets
	iis	- the array of inner subdomains,
	ois	- the array of outer subdomains, can be PETSC_NULL

Notes: this is merely a convenience subroutine that walks each list, destroys each IS on the list, and then frees the list.
