127    MatRegisterDynamic - Adds a new matrix type
128 
129    Synopsis:
130    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
131 
132    Not Collective
133 
134    Input Parameters:
135 +  name - name of a new user-defined matrix type
136 .  path - path (either absolute or relative) the library containing this solver
137 .  name_create - name of routine to create method context
138 -  routine_create - routine to create method context
139 
140    Notes:
141    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
142 
143    If dynamic libraries are used, then the fourth input argument (routine_create)
144    is ignored.
145 
146    Sample usage:
147 .vb
148    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
149                "MyMatCreate",MyMatCreate);
150 .ve
151 
152    Then, your solver can be chosen with the procedural interface via
153 $     MatSetType(Mat,"my_mat")
154    or at runtime via the option
155 $     -mat_type my_mat
156 
157    Level: advanced
158 
159    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
160          If your function is not being put into a shared library then use VecRegister() instead
