NAME

       continuation_option - send options to the continuation algorithm

DESCRIPTION

       This class is used to send options to the continuation function (see continuation(4)).

FLAGS

       tol

       max_iter
              These  options  are  transmitted  to  the damped_newton algorithm called during the
              continuation algorithm.

       ini_delta_parameter

       max_delta_parameter

       max_delta_parameter
              These options control the continuation parameter  evolution  along  the  branch  of
              solution.  When using the Keller continuation, these options control the arc-length
              parameter.

       n_adapt
              When non-zero allows one to activate the  optional  mesh  adaptation  feature  (see
              adapt(4)) embedded in the continuation algorithm.
