MATSELL
MATSELL = "sell" - A matrix type to be used for sparse matrices. This matrix type is identical to MATSEQSELL when constructed with a single process communicator,
and MATMPISELL otherwise. As a result, for single process communicators,
MatSeqSELLSetPreallocation is supported, and similarly MatMPISELLSetPreallocation is supported
for communicators controlling multiple processes. It is recommended that you call both of
the above preallocation routines for simplicity.
Options Database Keys
-mat_type sell -sets the matrix type to "sell" during a call to MatSetFromOptions()
Developer Notes
Subclasses include MATSELLCUSP, MATSELLCUSPARSE, MATSELLPERM, MATSELLCRL, and also automatically switches over to use inodes when
enough exist.
