MatRegisterDynamic

Adds a new matrix type

Synopsis

PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
Not Collective

Input Parameters

name - name of a new user-defined matrix type
path - path (either absolute or relative) the library containing this solver
name_create - name of routine to create method context
routine_create - routine to create method context

Notes

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

If dynamic libraries are used, then the fourth input argument (routine_create) is ignored.

Sample usage

   MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
               "MyMatCreate",MyMatCreate);

Then, your solver can be chosen with the procedural interface via

    MatSetType(Mat,"my_mat")
or at runtime via the option
    -mat_type my_mat

Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values. If your function is not being put into a shared library then use VecRegister() instead
