Details:

According to the filter help:

"If the fourth argument SI is provided, it is taken as the initial state of
the system and the final state is returned as SF. The state vector is a column
vector whose length is equal to the length of the longest coefficient vector
minus one."

But if I do


filter( [ 1, 1, 3 ], [ 1, 1, 4 ], [ 1; 3; 5 ], [ 1; 1 ] )


in octave-3.5.0+ I get

error: filter: first dimension of SI must be of length max (length (a), length
(b)) - 1

No such bug in octave-3.4.
