int o2scl::ode_bv_shoot< func_t, vec_t, vec_int_t >::solve_final_value ( double  x0, double  x1, double  h, size_t  n, vec_t &  ystart, vec_t &  yend, vec_int_t &  index, vec_t &  yerr, vec_t &  dydx_end, func_t &  derivs  )

inline

Given the n initial values of the functions in ystart, this function integrates the ODEs specified in derivs over the interval from x0 to x1 with an initial stepsize of h. The final values of the function are given in yend, the derivatives in dydx_end, and the associated errors are given in yerr. The initial values of yend and yerr are ignored.
