# MATCSRPERM

MATCSRPERM = "CSRPERM" - A matrix type to be used for sparse matrices. This matrix type is identical to MATSEQCSRPERM when constructed with a single process communicator, and MATMPICSRPERM otherwise. As a result, for single process communicators, MatSeqCSRPERMSetPreallocation is supported, and similarly MatMPICSRPERMSetPreallocation is supported for communicators controlling multiple processes. It is recommended that you call both of the above preallocation routines for simplicity.

### Options Database Keys
