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

     The '"syMatrix"' class is the class of symmetric matrices in
     non-packed storage.  Only the upper triangle or the lower triangle
     is stored.

_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("syMatrix",
     ...)'.

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

     '_u_p_l_o': Object of class '"character"'. Must be either "U", for
          upper triangular, and "L", for lower triangular.

     '_x': Object of class '"numeric"'. The numeric values that
          constitute the matrix, stored in column-major order.

     '_D_i_m': Object of class '"integer"'. The dimensions of the matrix
          which must be a two-element vector of non-negative integers.

     '_n_o_r_m': Object of class '"numeric"'. A named numeric vector of
          norms of the matrix.  Some possible components are '"O"', the
          one norm; '"I"', the infinity norm; '"F"', the Frobenius
          norm; and '"M"', the maximum absolute value.

     '_r_c_o_n_d': Object of class '"numeric"'. A named numeric vector of
          reciprocal condition numbers in either the 1-norm '"O"' or
          the infinity norm '"I"'.

     '_f_a_c_t_o_r_i_z_a_t_i_o_n': Object of class '"list"'.  A named list of
          factorizations that have been computed for the matrix.

_E_x_t_e_n_d_s:

     Class '"geMatrix"', directly. Class '"Matrix"', by class
     '"geMatrix"'.

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

     _c_o_e_r_c_e 'signature(from = "syMatrix", to = "geMatrix")'

     _c_o_e_r_c_e 'signature(from = "syMatrix", to = "matrix")'
