s	Specifies a second-order section filter. s is an L-by-6 matrix. Each row of s contains the coefficients of one section as [b0 b1 b2 1 a1 a2].
g	Specifies the gain of the filter. g is a real number.

Name	Description
b	Returns the numerator of the filter. b is a real vector.
a	Returns the denominator of the filter. a is a real vector.
