A system-theoretic appropriate realization of the empty matrix concept

An algebraic realization of the empty matrix concept that is appropriate for system-theoretic applications is proposed. The utility of the realization of the empty matrix concept and the deficiencies of the current MATLAB realization of this concept are demonstrated using examples. These examples fully delineate how the empty matrix concept can be utilized to transparently handle static and for single-vector-input, single-vector-output systems within the more general context of dynamic, two-vector-input, two-vector-output systems
