Thus must be cast with a (<A HREF="../Sys/PetscObject.html#PetscObject">PetscObject</A>), for example,
<A HREF="../Sys/PetscObjectName.html#PetscObjectName">PetscObjectName</A>((<A HREF="../Sys/PetscObject.html#PetscObject">PetscObject</A>)mat,name);

Notes: This is used in a small number of places when an object NEEDS a name, for example when it is saved to MATLAB with that variable name.
Use <A HREF="../Sys/PetscObjectSetName.html#PetscObjectSetName">PetscObjectSetName</A>() to set the name of an object to what you want. The AMS viewer requires that no two published objects
share the same name.
<P>
Developer Note: this needs to generate the exact same string on all ranks that share the object. The current algorithm may not always work.
