Member of the filter implementation class.

Syntax

[f, g] = latcfilt(k, x)

[f, g] = latcfilt(k, 1, x)

[f, g] = latcfilt(k, v, x)

[f, g, final] = latcfilt(k, x, 'ic', initial)

[f, g, final] = latcfilt(k, 1, x, 'ic', initial)

[f, g, final] = latcfilt(k, v, x, 'ic', initial)

Description

Uses a lattice filter to filter a signal. latcfilt works column-wise for matrices.

Examples

Inputs

Name	Description
k	Specifies the lattice reflection coefficients. k is a real vector or matrix.
v	Specifies the lattice ladder coefficients. v is a real vector or the integer 1.
x	Specifies the signal to filter. x is a real vector or matrix.
'ic'	Tells LabVIEW that the next listed input is initial.
initial	Specifies the initial states. initial is a real vector or matrix.

Outputs

Name	Description
f	Returns the minimum-phase filtered signal. If v is 1, f returns the all-pole filtered signal. f is a real vector or matrix.
g	Returns the maximum-phase filtered signal. If v is 1, g returns the all-pass filtered signal. g is a real vector or matrix.
final	Returns the final states. final is a real vector or matrix.

Examples

K = [0.1, 0.2, 0.8];
X = 0:0.01:1;
[F, G] = latcfilt(K, X)
