Abstract
A numerical algorithm for locating polar singularities of
functions defined on a discrete set of points of a simple closed
contour in the complex plane is examined. The algorithm uses
the Faber-Pad ́e approximation of the function and the fact that
the zeros of its denominator give us approximations of the poles
of function. The numerical performance of the algorithm is being
analyzed on test issues.
