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

     The class of positive-definite, symmetric matrices.

     Objects can be created by calls of the form 'new("pdmatrix",
     ...)'. More frequently they are created by coercing a 'pdMat'
     object to the 'pdmatrix' class.

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

     '._D_a_t_a': Object of class '"matrix"', which should be a numeric
          matrix.

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

     Class '"matrix"', from data part. Class '"structure"', by class
     "matrix". Class '"array"', by class "matrix". Class '"vector"', by
     class "matrix".

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

     _c_o_e_r_c_e 'signature(from = "matrix", to = "pdmatrix")': create a
          'pdmatrix' object from a matrix (does not check for symmetry
          or positive-definiteness)
