Function Synopsis

[h,t]=impz(b,a,N,Fs)

Help text

IMPZ	Impulse response of digital filter
	[H,T] = IMPZ(B,A) computes the impulse response of the filter B/A 
	choosing the number of samples for you, and returns the response in 
	column vector H and a vector of times (or sample intervals) in T 
	(T = [0 1 2 ...]').

	[H,T] = IMPZ(B,A,N) computes N samples of the impulse response.
	If N is a vector of integers, the impulse response is computed
	only at those integer values (0 is the origin).

	[H,T] = IMPZ(B,A,N,Fs) computes N samples and scales T so that
	samples are spaced 1/Fs units apart.  Fs is 1 by default.

	[H,T] = IMPZ(B,A,[],Fs) chooses the number of samples for you and scales
	T so that samples are spaced 1/Fs units apart.

	IMPZ with no output arguments plots the impulse response using
	STEM(T,H) in the current figure window.

	See also IMPULSE in the Controls Toolbox for continuous systems.
