Function Synopsis

[z,p,k] = tf2zp(num,den)

Help text

TF2ZP	Transfer function to zero-pole conversion.
	[Z,p,k] = TF2ZP(NUM,den)  finds the zeros, poles, and gains:

		          (s-z1)(s-z2)...(s-zn)
		H(s) =  K ---------------------
		          (s-p1)(s-p2)...(s-pn)

	from a SIMO transfer function in polynomial form:

		        NUM(s)
		H(s) = -------- 
		        den(s)

	Vector DEN specifies the coefficients of the denominator in 
	descending powers of s.  Matrix NUM indicates the numerator 
	coefficients with as many rows as there are outputs.  The zero
	locations are returned in the columns of matrix Z, with as many 
	columns as there are rows in NUM.  The pole locations are returned
	in column vector P, and the gains for each numerator transfer 
	function in vector K.
