Parameters:

matrix
subsystem – BitVector with states many entries. Only states in the given subsystem are kept. Transitions leading to a state outside of the subsystem will be removed (but the corresponding row is kept, possibly yielding empty rows). The ECs are then identified on the subsystem.

add_sink_row_states – BitVector with states many entries. If add_sink_row_states is true for at least one state of an eliminated EC, a row is added to the new state (representing the choice to stay at the EC forever).
add_self_loop_at_sink_states – if true, such rows get a selfloop (with value 1). Otherwise, the row remains empty.
