116

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