PCBJacobiGetSubSLES

Gets the local SLES contexts for all blocks on this processor.

#include "petscpc.h" 
int PCBJacobiGetSubSLES(PC pc,int *n_local,int *first_local,SLES **sles)

Note Collective

pc -the preconditioner context

	n_local	- the number of blocks on this processor, or PETSC_NULL
	first_local	- the global number of the first block on this processor, or PETSC_NULL
	sles	- the array of SLES contexts

After PCBJacobiGetSubSLES() the array of SLES contexts is not to be freed.

Currently for some matrix implementations only 1 block per processor is supported.

You must call SLESSetUp() or PCSetUp() before calling PCBJacobiGetSubSLES().
