_D_e_s_c_r_i_p_t_i_o_n:

     Attributes 'structName' and 'noCorrelation', with the values of
     the corresponding arguments to the method function, are appended
     to 'object' and its class is changed to 'summary.pdMat'.

_U_s_a_g_e:

     ## S3 method for class 'pdMat':
     summary(object, structName, noCorrelation, ...)

_A_r_g_u_m_e_n_t_s:

  object: an object inheriting from class 'pdMat', representing a
          positive definite matrix.

structName: an optional character string with a description of the
          'pdMat' class. Default depends on the method function:
          '"Blocked"' for 'pdBlocked', '"Compound Symmetry"' for
          'pdCompSymm', '"Diagonal"' for 'pdDiag', '"Multiple of an
          Identity"' for 'pdIdent', '"General Positive-Definite,
          Natural Parametrization"' for 'pdNatural', '"General
          Positive-Definite"' for 'pdSymm', and 'data.class(object)'
          for 'pdMat'.

noCorrelation: an optional logical value indicating whether
          correlations are to be printed in 'print.summary.pdMat'.
          Default depends on the method function: 'FALSE' for 'pdDiag'
          and 'pdIdent', and 'TRUE' for all other classes.

     ...: some methods for this generic require additional arguments. 
          None are used in this method.

_V_a_l_u_e:

     an object similar to 'object', with additional attributes
     'structName' and 'noCorrelation', inheriting from class
     'summary.pdMat'.
