Syntax

[b, a] = prony(h, m, n)

Uses Prony's method to design an IIR filter with a prescribed time domain impulse response.

Name	Description
h	Specifies a time domain impulse response. h is a vector.
m	Specifies the numerator order. m is a positive integer.
n	Specifies the denominator order. n is a positive integer.

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

The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine	Yes
Supported on RT targets	Yes
Suitable for bounded execution times on RT	Not characterized

b1 = [1];
a1 = [1, 0.2, -0.02, 1];
h = impzd(b1, a1, 10);
m = 2;
n = 3;
[b2, a2] = prony(h, m, n)
