A computationally efficient implementation of the Levinson algorithm in two steps that dramatically reduces the computational cost is presented. The algorithm uses the generalised Levinson recursion for block matrices as a first step and the Gohberg-Semencul formula as a second step, saving ~75% in terms of the computational cost for a typical two-channel deconvolution problem
