ab: Summary: We observe that successive applications of known results from the
    theory of positive systems lead to an efficient general algorithm for
    positive realizations of transfer functions. We give two examples to
    illustrate the algorithm, one of which complements an earlier result of
    {\it L. Benvenuti} and {\it L. Farina} [Syst. Control Lett. 36, No. 4,
    261‒266 (1999; Zbl 0915.93014)]. Finally, we improve a lower-bound of
    [{\it B. Nagy} and {\it M. Matolcsi}, A lower-bound on the dimension of
    positive realizations, IEEE Trans. Circuits Syst. I 50, 782‒784
    (2003)] to indicate that the algorithm is indeed efficient in general.
