MatSeqAIJRegister#

Adds a new sub-matrix type for sequential MATSEQAIJ matrices

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatSeqAIJRegister(const char sname[], PetscErrorCode (*function)(Mat, MatType, MatReuse, Mat *))

Not Collective

Input Parameters#

name - name of a new user-defined matrix type, for example MATSEQAIJCRL
function - routine to convert to subtype

Notes#

MatSeqAIJRegister() may be called multiple times to add several user-defined solvers.

Then, your matrix can be chosen with the procedural interface at runtime via the option

-mat_seqaij_type my_mat
