MATAIJCRL
MATAIJCRL = "aijcrl" - A matrix type to be used for sparse matrices. This matrix type is identical to MATSEQAIJCRL when constructed with a single process communicator,
and MATMPIAIJCRL 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.
