# MATAIJMKL

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, and 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.
