setpname (System Identification Toolbox)

Assign mnemonic parameter names to black box model structures.

Syntax

```
model = setpname(model)
```

Description

model is an idmodel object of idarx, idpoly or idss type. The returned model has the `PName' property set to a cell array of strings that correspond to the symbols used in this manual to describe the parameters.

For single input idpoly models, the parameters are called 'a1', 'a2', ...,'fn', just as defined in Section Polynomial Representation of Transfer Functions.

For multi-input idpoly models, the b- and f-parameters have the output/input channel number in parenthesis as in 'b1(1,2)', 'f3(1,2)' etc.

For idarx models, the parameter names are as in 'Ar(ky,ku)' for the ky-ku entry of the matrix in (Equation 3-46) and similarly for the B-parameters.

For idss models the parameters are named for the matrix entries they represent, like 'A(4,5)', 'K(2,3)' etc.

This function is particularly useful when certain parameters are to be fixed. See the property 'FixedParameter' under Algorithm Properties.
