This matrix inherits from MATSEQDENSE when constructed with a single process communicator, and from MATMPIDENSE otherwise. One can also call MatConvert for an inplace conversion to or from the MATSEQDENSE or MATMPIDENSE type (depending on the communicator size) without data copy.
-mat_type plapack | - sets the matrix type to "plapack" during a call to MatSetFromOptions() | |
-mat_plapack_nprows <n> | - number of rows in processor partition | |
-mat_plapack_npcols <n> | - number of columns in processor partition | |
-mat_plapack_nb <n> | - block size of template vector | |
-mat_plapack_nb_alg <n> | - algorithmic block size | |
-mat_plapack_ckerror <n> | - error checking flag |
