If created with a single process communicator, this matrix type inherits from MATSEQSBAIJ. Otherwise, this matrix type inherits from MATMPISBAIJ. Hence for single process communicators, MatSeqSBAIJSetPreallocation is supported, and similarly MatMPISBAIJSetPreallocation is supported for communicators controlling multiple processes. It is recommended that you call both of the above preallocation routines for simplicity. One can also call MatConvert for an inplace conversion to or from the MATSEQSBAIJ or MATMPISBAIJ type (depending on the communicator size) without data copy.
