(^5) In the Enter snapshot times to linearize dialog box, in the Simulation Snapshot
Times field, enter one or more snapshot times at which to linearize. For this
example, enter 10 to extract the operating point at this simulation time.
TipTo linearize the model at several operating points, specify a vector of simulation
times in the Simulation Snapshot Times field. For example, entering [1 10]
results in an array of two linear models, one linearized at t = 1 and the other at t =
10.

Generate the simulation-snapshot operating point. Click Take Snapshots.
The operating point op_snapshot1 appears in the Linear Analysis Workspace. In the
Operating Point drop-down list, this operating point is now selected as the
operating point to be used for linearization.
(^7) Linearize the model at the specified operating point and generate a bode plot of the
result.
Click Bode. The Bode plot of the linearized plant appears, and the
linearized plant linsys1 appears in the Linear Analysis Workspace.
