As is shown in this screenshot, the mincx result states the f-radius saturation information. I wonder what this f-radius saturation information means, and how it influence the LMI results. (In this screenshot the f-radius saturation is 100% of R=1e9. However, sometimes in other case, it is only 6%.)
