A transfer matrix can be obtained for any linear system to analyze its dynamics and other properties; each element of a transfer matrix is a transfer function relating a particular input variable to an output variable. To determine the expression for the transfer function or transfer matrix, the Laplace Transforms of the above equations are taken. 2. For a multi-input, multi-output (MIMO) system with \(m\) inputs and \(p\) outputs, this results in a \(p \times m\) matrix of rational functions of \(z\). i = ±1), with a nearest–neighbor is the transfer function of the system (8. The characteristic equation of the system is det 0s I A> @ > @. e.
