Abstract

A direct and simple numerical method is presented for calculating the transfer function matrix of a linear time invariant multivariable system (A, B, C). The method is based on the matrix-determinant identity, and it involves operations with an auxiliary vector on the matrices. The method is computationally faster compared to Liverrier and Danilevsky methods.
