More precisely, we use positive definite matrices to denote full multi\-dimensional interconnections, while using nonnegative definite matrices to denote partial multi\-dimensional interconnections. We prove that the generalized graph Laplacian inherits the spectral properties of the graph Laplacian. As an application, we use the generalized graph Laplacian to establish a distributed consensus algorithm for agents described by multi\-dimensional integrators."]
