• If linsys is an array of state-space models, Advisor is an array of
  LinearizationAdvisor objects with the same dimensions as linsys.

LinearizationAdvisor objects store linearization diagnostic information for individual
linearized blocks. For an example of troubleshooting linearization results using a
LinearizationAdvisor object, see “Troubleshoot Linearization Results at Command
Line” on page 4-42.

Loop Transfer Function

The loop transfer function at a point is the point-to-point open-loop transfer function from
an additive disturbance at a point to a measurement at the same point.

To compute the loop transfer function at an analysis point, x, the software adds a
linearization output, inserts a loop break, and adds a linearization input, dx. The software
computes the transfer function from dx to x, which is equal to the loop transfer function
at x.
