<A HREF="../Mat/MATAIJPERM.html#MATAIJPERM">MATAIJPERM</A> = "AIJPERM" - A matrix type to be used for sparse matrices. This matrix type is identical to MATSEQAIJPERM when constructed with a single process communicator,
and MATMPIAIJPERM otherwise. As a result, for single process communicators,
<A HREF="../Mat/MatSeqAIJSetPreallocation.html#MatSeqAIJSetPreallocation">MatSeqAIJSetPreallocation</A>() is supported, and similarly <A HREF="../Mat/MatMPIAIJSetPreallocation.html#MatMPIAIJSetPreallocation">MatMPIAIJSetPreallocation</A>() is supported
for communicators controlling multiple processes. It is recommended that you call both of
the above preallocation routines for simplicity.
