clone

Copy online parameter estimation System object

Syntax

obj_clone = clone(obj)

Description

obj_clone = clone(obj) creates a copy of the online parameter estimation System object™, obj, with the same property values. If the object you clone is locked, the new object is also locked.

clone is not supported for code generation using MATLAB^® Coder™.

Note

If you want to copy an existing System object and then modify properties of the copied object, use the clone command. Do not create additional objects using syntax obj2 = obj. Any changes made to the properties of the new System object created this way (obj2) also change the properties of the original System object (obj).

Examples

Clone an Online Estimation System Object

Create a System object™ for online estimation of an ARX model with default properties.

obj = recursiveARX

obj = 
  recursiveARX with properties:

                             A: []
                             B: []
                      InitialA: [1 2.2204e-16]
                      InitialB: [0 2.2204e-16]
           ParameterCovariance: []
    InitialParameterCovariance: [2x2 double]
              EstimationMethod: 'ForgettingFactor'
              ForgettingFactor: 1
              EnableAdaptation: true
                       History: 'Infinite'
               InputProcessing: 'Sample-based'
                      DataType: 'double'

Use clone to generate an object with the same properties as the original object.

obj2 = clone(obj)

obj2 = 
  recursiveARX with properties:

                             A: []
                             B: []
                      InitialA: [1 2.2204e-16]
                      InitialB: [0 2.2204e-16]
           ParameterCovariance: []
    InitialParameterCovariance: [2x2 double]
              EstimationMethod: 'ForgettingFactor'
              ForgettingFactor: 1
              EnableAdaptation: true
                       History: 'Infinite'
               InputProcessing: 'Sample-based'
                      DataType: 'double'
