ozone_ode_test


ozone_ode_test, an Octave code which calls ozone_ode(), which defines a stiff system of four ordinary differential equations (ODE) that simulate the daily variation in atmospheric ozone concentration.

This problem apparently was too difficult for the Octave versions of ode23() or ode45(), or for my version of midpoint(). Instead, I had to switch to the lsode() solver, which in turn uses a nonstandard arrangement for the arguments.
