Mathematical Foundations for Efficient Structural Controllability and Observability Analysis of Complex Systems

<table>Adding inputs to every right-unmatched node might leave inaccessible nodes (grey in the figure). To overcome this problem, one may either add wirings (dashed line) from any existing input or include new dedicated inputs (<svg height="11.825" id="M156" style="vertical-align:-3.13504pt" version="1.1" viewbox="0 0 15.6 11.825" width="15.6" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
