This matrix inherits from MATSEQAIJ when constructed with a single process communicator, and from MATMPIAIJ otherwise. As a result, for single process communicators, MatSeqAIJSetPreallocation is supported, and similarly MatMPIAIJSetPreallocation 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 MATSEQAIJ or MATMPIAIJ type (depending on the communicator size) without data copy.
