Abstract:
In this short note, the problem of the choice of the expansion point in Krylov-based model reduction is addressed and the RK-ICOP algorithm for the automatic choice of a single expansion point for moment matching is revisited. This algorithm is numerically e±cient, thus suitable for large-scale systems, and does not require any simulation or expert knowledge of the original system. In addition, a compact Matlab implementation is suggested.
