    "abstract": "Matrix representations of the Maxwell equations are well-known. However, all\nthese representations lack an exactness or/and are given in terms of a {\\em\npair} of matrix equations. We present a matrix representation of the Maxwell\nequation in presence of sources in a medium with varying permittivity and\npermeability. It is shown that such a representation necessarily requires $8\n\\times 8$ matrices and an explicit representation for them is presented.",
