Function Synopsis

[b,a] = stmcb( x, u_in, q, p, niter, a_in )

Help text

STMCB	Compute linear model via Steiglitz-McBride iteration
	[B,A] = stmcb(X,NB,NA) finds the coefficients of the system 
	B(z)/A(z) with approximate impulse response X, NA poles and 
	NB zeros.

	[B,A] = stmcb(X,NB,NA,N) uses N iterations.  N defaults to 5.

	[B,A] = stmcb(X,NB,NA,N,Ai) uses the vector Ai as the initial 
	guess at the denominator coefficients.  If you don't specify Ai, 
	STMCB uses [B,Ai] = PRONY(X,0,NA) as the initial conditions.

	[B,A] = STMCB(X,U,NB,NA,N,Ai) finds the system coefficients B and 
	A of the system which, given U as input, has X as output.  N and Ai
	are again optional with default values of N = 5, [B,Ai] = PRONY(X,0,NA).
	X and U must be the same length.

	See also PRONY and LEVINSON, and OE in the System 
	Identification Toolbox.
