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

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

_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:

     There are (very simplistic) group methods (see, e.g., 'Arith')

     _A_r_i_t_h 'signature(e1 = "dMatrix", e2 = "dMatrix")': ... 

     _A_r_i_t_h 'signature(e1 = "dMatrix", e2 = "numeric")': ... 

     _A_r_i_t_h 'signature(e1 = "numeric", e2 = "dMatrix")': ... 

     _M_a_t_h 'signature(x = "dMatrix")': ... 

     _M_a_t_h_2 'signature(x = "dMatrix", digits = "numeric")': ...

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

     'dgeMatrix-class', 'dgCMatrix-class', and 'Matrix-class'.
