Iterates the calculation of Haydock coefficients and states in the retarded regime and saves them for later retrieval.


  • new(metric=>$m, polarization=>$p, nh=>$nh[, keepStates=>$k, smallH=>$s])

    Initializes an Ph::WE::R2::AllH object. $m is the retarded metric to use, $p is the polarization of the field, $nh is the maximum number of desired coefficients to calculate, $k is a flag, non zero to save the Haydock states, $s is a number to be considered negligible. Other arguments are as in Photonic::WE::R2::OneH.

  • run

    Runs the iteration to completion.

  • All the Photonic::WE::R2::OneH methods

ACCESORS (read only)

  • states

    Array of Haydock states

  • as

    Array of Haydock a coefficients

  • bs
