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.
