This WebApp aims to illustrate how the state space representation works.
Use the slider to change the input amplitude (for a step input).
Drag the poles or the zero in the pole diagram to change the vector field corresponding to the system in real time.
Click on the vector field to add a "particle". Left click adds a single particle, right click adds a source.
Edit the state space equations to change the vector field (and poles).

Press OK to see the function of each element in the WebApp.
