124    MatRegisterDynamic - Adds a new matrix type
125 
126    Synopsis:
127    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
128 
129    Not Collective
130 
131    Input Parameters:
132 +  name - name of a new user-defined matrix type
133 .  path - path (either absolute or relative) the library containing this solver
134 .  name_create - name of routine to create method context
135 -  routine_create - routine to create method context
136 
137    Notes:
138    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
139 
140    If dynamic libraries are used, then the fourth input argument (routine_create)
141    is ignored.
142 
143    Sample usage:
144 .vb
145    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
146                "MyMatCreate",MyMatCreate);
147 .ve
148 
149    Then, your solver can be chosen with the procedural interface via
150 $     MatSetType(Mat,"my_mat")
151    or at runtime via the option
152 $     -mat_type my_mat
153 
154    Level: advanced
155 
156    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
157          If your function is not being put into a shared library then use VecRegister() instead
