numfilterbanks

Number of scattering filter banks

Description

example

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

Examples
