Abstract
In the above-mentioned paper by Lim et al. (1996) a numerical example is given to show that the Nevanlinna-Pick interpolation formulas appearing in Khargonekar and Tannenbaum (1985) and Krein and Nudel´man (1977) are incorrect. By comparing the paper of Krein and Nudel´man with Adamjan (1971) we illustrate that the correct formulas are obtained by simply taking the transpose of the Pick matrix given in the first two above mentioned papers.
