NAME
rk_shooter - Object that performs one cycle of a shooting
method for the boundary value problem.
DESCRIPTION
This object is used in conjunction with a function object
that computes the right side of the system of ordinary
differential equations. For details on shooting method see
Numerical Recipes in C, by W.H.Press, et all, Cambridge
University Press, 1988, p. 602.
SUPERCLASS
rkqc_solver
MESSAGES
shoot! this method performs one cycle of shooting method.
It solves the initial problem three times and
changes initial conditions according to Newton-
Raphson procedure. See pp. 603-605 of the previously referenced book.
