Plot Step Response for Specific Parameter Combination and Snapshot Time

Suppose you want to examine only the step response for the model obtained by

linearizing the watertank model at t = 3, for A = 10 and b = 4. To do so, you can use

the SamplingGrid property of linsys, which is specified as a structure. When you

perform batch linearization, the software populates SamplingGrid with information

regarding the variable values used to obtain the model. The variable values include each

parameter that you vary and the simulation snapshot times at which you linearize the

model. For example:

linsys(:,:,1).SamplingGrid

ans =

A: 10

b: 4

Time: 0

Here linsys(:,:,1) refers to the first model in linsys. This model was obtained at

simulation time t = 0, for A = 10 and b = 4.
