c=sos2cell(s) converts an L-by-6 second-order-section matrix s given by:
s = [B1 A1
B2 A2
...
BL AL]
to a cell array c = { {B1},{A1}, {B2},{A2}, ... {BL},{AL}} where each
numerator vector Bi and denominator vector Ai contains the coefficients of a
linear or quadratic polynomial. If the polynomial is linear, the coefficients
zero-padded on the right
c=sos2cell(s,g) adds a leading gain term to the start of the cell array as:
c={ {[g,1]},{B1},{A1}, {B2},{A2}, ... {BL},{AL}}
