Enable zero-crossing detection

Enable zero-crossing detection to ensure that the software computes the linear system
characteristics at the following simulation times:

• The exact snapshot times, specified in Snapshot times on page 16-152.

As shown in the following figure, when zero-crossing detection is enabled, the

variable-step Simulink solver simulates the model at the snapshot time Tsnap. Tsnap may

lie between the simulation time steps Tn-1 and Tn which are automatically chosen by

the solver.
