For example, pt = 'y1m'.

• Cell array of character vectors or string array — Specifies multiple analysis point
  names. For example, pt = {'y1m','y2m'}.


• Positive integer or — Analysis point index.

To determine the index of an analysis point, type s. The software displays the contents

of s in the MATLAB command window, including the analysis points indices.

For example, pt = 1.

• Vector of positive integers — Specifies multiple analysis point indices. For example, pt
  = [1 2].

Analysis Points

Analysis points, used by the slLinearizer and slTuner interfaces, identify locations

within a model that are relevant for linear analysis and control system tuning. You use

analysis points as inputs to the linearization commands, such as getIOTransfer,

getLoopTransfer, getSensitivity, and getCompSensitivity. As inputs to the

linearization commands, analysis points can specify any open-loop or closed-loop transfer

function in a model. You can also use analysis points to specify design requirements when

tuning control systems using commands such as systune.

Location refers to a specific block output port within a model or to a bus element in such

an output port. For convenience, you can use the name of the signal that originates from

this port to refer to an analysis point.

You can add analysis points to an slLinearizer or slTuner interface, s, when you

create the interface. For example:

s = slLinearizer('scdcascade',{'u1','y1'});

Alternatively, you can use the addPoint command.

To view all the analysis points of s, type s at the command prompt to display the interface

contents. For each analysis point of s, the display includes the block name and port

number and the name of the signal that originates at this point. You can also

programmatically obtain a list of all the analysis points using getPoints.
