MATAIJMKL = “AIJMKL” - A matrix type to be used for sparse matrices. This matrix type is identical to
MATSEQAIJMKL when constructed with a single process communicator,
MATMPIAIJMKL 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.
