nwidPEMOptions class

Options set for full network identification with nwidPEM.

Construction

• options = nwidPEMOptions  creates the default options set.
• options = nwidPEMOptions(Name=Value,...)  creates a custom options set, with the default options overriden by the name-value arguments.

Properties

• random_init

  logical scalar

  Logical variable specifying if the network parameters are randomly initialized (leading to a stable system) or the initial values are used. When randomly initialized, sets of parameters are drawn from a GWN distribution until a stable system is obtained.

• init_attempts

  positive integer

  Number of attempts at finding a stable initialization. 200 by default.

• pemopts

  greyestOptions

  Option set for PEM estimation, see the documentation for greyestOptions of the System Identification Toolbox. By default, stability of the estimated model is enforced (EnforceStability = true).
