Help text

SOS2SS	Second-order sections to state space linear system model conversion
	[A,B,C,D] = SOS2SS(SOS) returns the state space matrices A, B, C and D
	of the discrete-time system given by SOS in second-order sections form.
	SOS is an L by 6 matrix which contains the coefficients of each 
	second-order section in its rows:
	    SOS = [ b01 b11 b21  a01 a11 a21 
	            b02 b12 b22  a02 a12 a22
	            ...
	            b0L b1L b2L  a0L a1L a2L ]
	The system transfer function is the product of the second-order transfer
	functions of the sections.  Each row of the SOS matrix describes
	a 2nd order transfer function as
	    b0k +  b1k z^-1 +  b2k  z^-2
	    ----------------------------
	    a0k +  a1k z^-1 +  a2k  z^-2
	where k is the row index.
