Define a state-space system with n states, m inputs, and p outputs.
Extract a subsystem with three inputs (u1(t), u2(t), and u4(t)), one output (y2(t)), and three states (x1(t), x3(t), and x6(t)).
Extract a subsystem in differential equation form with all of the inputs, two outputs (y1(t) and y2(t)), and the first state.
Extract a subsystem with three inputs (u1(t), u2(t), and u4(t)), output y2(t), and no states.
When the inputs, outputs, and states arguments are omitted, the Subsystem command returns the original system.
Extract a subsystem with no inputs, no outputs, and no states.
Extract subsystem with inputs u1(t), u2(t) and u3(t). Observe that index repetition and sorting are not relevant in a set.
Extract subsystem with inputs u1(t) and u3(t) and outputs y1(t) and y2(t).
