Creates a SeqAIJ from a MPIAIJ matrix by taking all its local rows and putting them into a sequential vector with mlocal rows and n columns. Where mlocal is the row count obtained with <A HREF="../Mat/MatGetLocalSize.html#MatGetLocalSize">MatGetLocalSize</A>() and n is the global column count obtained with <A HREF="../Mat/MatGetSize.html#MatGetSize">MatGetSize</A>()
