<A HREF="../Mat/MatConvert.html#MatConvert">MatConvert</A>() first creates a new matrix and then copies the data from
the first matrix. A related routine is <A HREF="../Mat/MatCopy.html#MatCopy">MatCopy</A>(), which copies the matrix
entries of one matrix to another already existing matrix context.
<P>
Cannot be used to convert a sequential matrix to parallel or parallel to sequential,
the MPI communicator of the generated matrix is always the same as the communicator
of the input matrix.
