<A HREF="../Mat/MatRegisterDynamic.html#MatRegisterDynamic">MatRegisterDynamic</A>() may be called multiple times to add several user-defined solvers.
<P>
If dynamic libraries are used, then the fourth input argument (routine_create)
is ignored.

<A HREF="../Mat/MatRegisterDynamic.html#MatRegisterDynamic">MatRegisterDynamic</A>("my_mat",/home/username/my_lib/lib/libO/solaris/mylib.a,
"MyMatCreate",MyMatCreate);
</PRE>
<P>
Then, your solver can be chosen with the procedural interface via
<pre>
<A HREF="../Mat/MatSetType.html#MatSetType">MatSetType</A>(<A HREF="../Mat/Mat.html#Mat">Mat</A>,"my_mat")
</pre>
or at runtime via the option
<pre>
-mat_type my_mat
</pre>
<P>
<P>
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 <A HREF="../Vec/VecRegister.html#VecRegister">VecRegister</A>() instead
