MATAIJCRL#

MATAIJCRL = “aijcrl” - A matrix type to be used for sparse matrices.

Options Database Key#

  • -mat_type aijcrl - sets the matrix type to “aijcrl” during a call to MatSetFromOptions()

Note#

This matrix type is identical to MATSEQAIJCRL when constructed with a single process communicator, and MATMPIAIJCRL 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.
