dfilt.latticear - Discrete-time, lattice, autoregressive filter

Syntax

Hd = dfilt.latticear(k)
Hd = dfilt.latticear

Description

Hd = dfilt.latticear(k) returns a discrete-time, lattice autoregressive filter, Hd, with lattice coefficients, k.

Hd = dfilt.latticear returns a default, discrete-time, lattice autoregressive filter, Hd, with k=[ ]. This filter passes the input through to the output unchanged.

The resulting filter states column vector is

Examples

Form a third-order lattice autoregressive filter structure for a dfilt object, Hd, using the following lattice coefficients:

k = [.66 .7 .44];
Hd = dfilt.latticear(k)
Hd =
             FilterStructure: 'Lattice Autoregressive (AR)'
                     Lattice: [0.6600 0.7000 0.4400]
            PersistentMemory: false
