param — Parameter samples

structure | structure array

Parameter samples for linearization, specified as one of the following:

• 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;

For more information, see “Specify Parameter Samples for Batch Linearization” on page

3-62.

If param specifies tunable parameters only, the software batch linearizes the model using

a single model compilation.

To compute the offsets required by the LPV System block, specify param, and set

options.StoreOffsets to true. You can then return additional linearization

information in info, and extract the offsets using getOffsetsForLPV.
