With these results, the interrogation of the controllability disposition of this class of functional differential control systems can be accomplished with astounding swiftness, in turn, providing the much desired implementation paradigm shift.enC++ codesCardinalityDetermining matricesEuclidean controllabilityComputational feasibilityElectronic implementationPermutationsDouble-delay control systemsArticle
