_D_e_s_c_r_i_p_t_i_o_n:

     A general numeric dense matrix in the S4 Matrix representation. 
     'dgeMatrix' is the _"standard"_ class for dense numeric matrices
     in the 'Matrix' package.

_O_b_j_e_c_t_s _f_r_o_m _t_h_e _C_l_a_s_s:

     Objects can be created by calls of the form 'new("dgeMatrix",
     ...)' or, more commonly, by coercion from the 'Matrix' class (see
     Matrix) or by 'Matrix(..)'.

_S_l_o_t_s:


     '_x': Object of class '"numeric"' - the numeric values contained in
          the matrix, in column-major order.

     '_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': a list of length two - inherited from class 'Matrix'.

     '_f_a_c_t_o_r_s': Object of class '"list"' - a list of factorizations of
          the matrix.

_M_e_t_h_o_d_s:
