Adaptive Filter Properties Reference

Like qfilts, adaptfilts are objects and have properties that govern their behavior and store some of the results of filtering operations. This section lists, in alphabetical order, the name of every property associated with adaptfilt objects. Note that not all adaptfilt objects have all of these properties. To view the properties of a particular adaptive filter, such as an adaptfilt.bap filter, use get with the object handle, like this:

• ha = adaptfilt.bap(32,0.5,4,1.0);
  get(ha)
      ResetBeforeFiltering: 'on'
       NumSamplesProcessed: 0
                 Algorithm: 'Block Affine Projection FIR Adaptive Filter'
              FilterLength: 32
              Coefficients: [1x32 double]
                    States: [35x1 double]
                  StepSize: 0.5000
           ProjectionOrder: 4
                 OffsetCov: [4x4 double]
  

get shows you the properties for ha and the values for the properties.
