Function Synopsis

[num, den] = ss2tf(a,b,c,d,iu)

Help text

SS2TF	State-space to transfer function conversion.
	[NUM,DEN] = SS2TF(A,B,C,D,iu)  calculates the transfer function:

		        NUM(s)          -1
		H(s) = -------- = C(sI-A) B + D
		        DEN(s)
	of the system:
		.
		x = Ax + Bu
		y = Cx + Du

	from the iu'th input.  Vector DEN contains the coefficients of the
	denominator in descending powers of s.  The numerator coefficients
	are returned in matrix NUM with as many rows as there are 
	outputs y.
