Recently I wrote a randomized algorithm for computing static-output-feedback for stabilizing a finite set of systems simultaneously.
I need a good library of test problems. Can you suggest such a liberary or reference ?
The mistake in the article that was already published (a few days ago) occurred under the responsibility of the journal's production team and not under my responsibility. I don't understand why I...
