pt = {'torque','Motor/PID','Engine Model/1'}

• Vector of linearization I/O objects — Create pt using linio. For example:

pt(1) = linio('scdcascade/setpoint',1,'input');

pt(2) = linio('scdcascade/Sum',1,'output');

Here, pt(1) specifies an input, and pt(2) specifies an output.

The interface adds all the points specified by pt and ignores their I/O types. The

interface also adds all 'loopbreak' type signals as permanent openings on page 15-

272.

param — Parameter samples
structure | structure array

Parameter samples for linearizing mdl, specified as:

• Structure — Vary the value of a single parameter by specifying param as a structure
  with the following fields:
  
  
  • Name — Parameter name, specified as a character vector or string. You can specify
    any model parameter that is a variable in the model workspace, the MATLAB
    workspace, or a data dictionary. If the variable used by the model is not a scalar
    variable, specify the parameter name as an expression that resolves to a numeric
    scalar value. For example, to use the first element of vector V as a parameter, use:
  
  
  
  

param.Name = 'V(1)';

• Value — Parameter sample values, specified as a double array.

For example, vary the value of parameter A in the 10% range:

param.Name = 'A';

param.Value = linspace(0.9*A,1.1*A,3);

• Structure array — Vary the value of multiple parameters. For example, vary the values
  of parameters A and b in the 10% range:

[A_grid,b_grid] = ndgrid(linspace(0.9*A,1.1*A,3),...

linspace(0.9*b,1.1*b,3));

params(1).Name = 'A';

params(1).Value = A_grid;

params(2).Name = 'b';

params(2).Value = b_grid;
