_D_e_s_c_r_i_p_t_i_o_n:

     The 'Matrix' class is a class contained by all actual classes in
     the 'Matrix' package.  It is a "virtual" class.

_S_l_o_t_s:

     Common to _all_ matrix object in the package:

     '_D_i_m': Object of class '"integer"' - the dimensions of the matrix
          - must be an integer vector with exactly two non-negative
          values.

     '_D_i_m_n_a_m_e_s': list of length two; each component containing NULL or
          a 'character' vector length equal the corresponding 'Dim'
          element.

_M_e_t_h_o_d_s:

     _d_i_m 'signature(x = "Matrix")': extract matrix dimensions 'dim'.

     _d_i_m_n_a_m_e_s 'signature(x = "Matrix")': extract 'dimnames'.

     _d_i_m_n_a_m_e_s<- 'signature(x = "Matrix", value = "list")': set the
          'dimnames' to a 'list' of length 2, see 'dimnames<-'.

     _s_h_o_w 'signature(object = "Matrix")': 'show' method for 'print'ing.

_A_u_t_h_o_r(_s):

_S_e_e _A_l_s_o:

     'dgeMatrix-class', 'dgCMatrix-class', and 'Matrix' for
     construction (and examples).
