MATCRL

MATCRL = "crl" - A matrix type to be used for sparse matrices. This matrix type is identical to MATSEQCRL when constructed with a single process communicator, and MATMPICRL 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.
