Syntax

nfb = numfilterbanks(sf)

Description

example

nfb = numfilterbanks(sf) returns the number of filter banks in the scattering decomposition framework, sf. The number of filter banks in a scattering decomposition framework is equal to ord − 1 where ord is the number of scattering orders.

Calculate the number of filter banks for the default scattering decomposition framework.

sf = waveletScattering
sf = 
  waveletScattering with properties:

        QualityFactors: [8 1]
              Boundary: 'periodic'
     SamplingFrequency: 1
             Precision: 'double'
    OversamplingFactor: 0
