getreg

Names of standard or custom regressors in nonlinear ARX model

Syntax

getreg(model)
getreg(model,subset)
R = getreg(model,subset)

Arguments

model

Name of the idnlarx model object.

subset

Has one of the following values: 'all', 'input', 'output', 'standard', 'custom', 'linear', and 'nonlinear'.

Description

getreg(model) returns the regressor expressions for all of the regressors in the nonlinear ARX model.

getreg(model,subset) returns the regressor expressions for a specified subset of the regressors, as follows:

• 'all' — All regressors.

• 'input' — Input regressors only.

• 'output' — Output regressors only.

• 'standard' — Standard regressors only.

• 'custom' — Custom regressors only.

• 'linear' — Regressors that are not used in the in the nonlinear block.

• 'nonlinear' — Regressors used in the nonlinear block.

  Note   You can use 'nl' as an abbreviation for 'nonlinear'.

R = getreg(model,subset) returns a cell array of strings of the regressors for a specified subset of the regressors. For multiple-output, returns a cell array of cell arrays.
