Syntax

[b, a] = latc2tf(k)

[b, a] = latc2tf(k, option)

[b, a] = latc2tf(k, v)

Description

Converts a lattice filter to a transfer function.

Examples

Inputs

Name	Description
k	Specifies the lattice reflection coefficients. k is a real vector.
v	Specifies the lattice ladder coefficients. v is a real vector.
option	Specifies the type of filter. option is a string that accepts the following values: 'FIR' General FIR filter. 'min' Minimum-phase FIR filter. 'max' Maximum-phase FIR filter. 'allpole' All-pole filter. 'allspace' All-pass filter.

Outputs

Name	Description
b	Returns the forward filter coefficients.
a	Returns the backward filter coefficients.

Examples

k = [0.1, 0.2, 0.5];
v = [0.9, 0.3, 0.4, 0.1];
[a, b] = latc2tf(k, v)
