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

     This generic function extracts the positive-definite matrix
     represented by `object'.

     This function is deprecated.  Use coersion to the `pdmatrix' class
     instead.

_U_s_a_g_e:

     pdMatrix(object)

_A_r_g_u_m_e_n_t_s:

  object: an object inheriting from class `pdMat', representing a
          positive definite matrix, which must have been initialized
          (i.e. `length(coef(object)) > 0').

_V_a_l_u_e:

     A `pdmatrix' object.

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

     `pdmatrix-class', `pdMat-class'
