A numerical implementation of the method of Kung and Lin is described.
It is a method to find the minimal degree approximant, given an approximation
error bound for the Hankel-norm approximation criterion for multivariable
After a brief review of the theory, all non standard computations
are described in detail.
Some comments on its numerical performance are given, guided by two illustrative
