# dfilt.latticemamin

Discrete-time, lattice, moving-average filter

## Syntax

`Hd = dfilt.latticemamin(k)Hd = dfilt.latticemamin`

## Description

`Hd = dfilt.latticemamin(k)` returns a discrete-time, lattice, moving-average, minimum phase, filter, `Hd`, with lattice coefficients `k`.

 Note   If the `k` coefficients define a minimum phase filter, the resulting filter in this structure is minimum phase. If your coefficients do not define a minimum phase filter, placing them in this structure does not produce a minimum phase filter.

`Hd = dfilt.latticemamin` returns a default discrete-time, lattice, moving-average, minimum phase, filter, `Hd`, with `k`=[ ]. This filter passes the input through to the output unchanged.

The resulting filter states column vector is

`$\left[\begin{array}{c}z\left(1\right)\\ z\left(2\right)\\ z\left(3\right)\end{array}\right]$`

## Examples

Form a third-order lattice, moving-average, minimum phase, filter structure for a `dfilt` object, `Hd`, using the following lattice coefficients.

```k = [.66 .7 .44]; Hd = dfilt.latticemamin(k) ```
