Example: If the previous three text fields read Start=500, Stop=1000, and Plot=3,
then DsTool will calculate 1000 points along a trajectory but will
only store the points indexed by 500, 503, 506,..., 998, and 1000 (the final condition is always
kept). Setting Plot for mappings may be thought of as studying the
th iterate of the map.
For vector fields, setting Plot
is useful when it is necessary to choose a small
integration step, but we do not want to see every plotted point.
If the current integrator is a fixed step algorithm (e.g., the Euler method or a standard fourth order Runge-Kutta method):
If the current integrator is a variable step algorithm (e.g., quality-control algorithms and the Bulirsch-Stoer method), then the value shown in the Step size field is used as an initial step size.
