It was left as an open question how to generalize the harmonic Rayleigh-Ritz approach for the MER This paper addresses this issue, and also introduces a refined Ritz method.
In case both p and q are polynomials of degree one, the rational harmonic Ritz approach is related to the standard harmonic Ritz method as follows.
The pole and zero placement in the harmonic approaches, although not of large influence, is an interesting future question; see [14] for some results for the standard harmonic Ritz method.
