117    MatRegisterDynamic - Adds a new matrix type
118 
119    Synopsis:
120    PetscErrorCode MatRegisterDynamic(char *name,char *path,char *name_create,PetscErrorCode (*routine_create)(Mat))
121 
122    Not Collective
123 
124    Input Parameters:
125 +  name - name of a new user-defined matrix type
126 .  path - path (either absolute or relative) the library containing this solver
127 .  name_create - name of routine to create method context
128 -  routine_create - routine to create method context
129 
130    Notes:
131    MatRegisterDynamic() may be called multiple times to add several user-defined solvers.
132 
133    If dynamic libraries are used, then the fourth input argument (routine_create)
134    is ignored.
135 
136    Sample usage:
137 .vb
138    MatRegisterDynamic("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
139                "MyMatCreate",MyMatCreate);
140 .ve
141 
142    Then, your solver can be chosen with the procedural interface via
143 $     MatSetType(Mat,"my_mat")
144    or at runtime via the option
145 $     -mat_type my_mat
146 
147    Level: advanced
148 
149    Notes: ${PETSC_ARCH} occuring in pathname will be replaced with appropriate values.
150          If your function is not being put into a shared library then use VecRegister() instead
