WebThe core ideas are (1) representation of the rational approximant in barycentric form with interpolation at certain support points and (2) greedy selection of the support points to avoid exponential instabilities. The name AAA stands for “adaptive Antoulas--Anderson” in honor of the authors who introduced a scheme based on (1).
WebThis paper deals with the general rational interpolation problem (GRIP) in the scalar case. In the recent work of Antoulas, Ball, Kang, and Willems the general solution to the GRIP has been derived in the framework of linear fractions using the so-called generating matrix as the main tool. flower power coffee tableWebinterpolation points coincide, we can reformulate the scalar RIP as a scalar minimal partial realization problem. We have generalized the case where all the data are given at one point to vector data [6] and even matrix data [17].
