# Forward-backward IIR filter that uses Gustafsson's method.
#
# Apply the IIR filter defined by `(b,a)` to `x` twice, first forward
# then backward, using Gustafsson's initial conditions [1]_.
#
# Let `y_fb` be the result of filtering first forward and then backward,
# and let `y_bf` be the result of filtering first backward then forward.
# Gustafsson's method is to compute initial conditions for the forward
# pass and the backward pass such that `y_fb == y_bf`.
