Talk:Linear matrix inequality

From Wikipedia, the free encyclopedia

This page needs cleanup. The convexity discussion is not needed in my opinion, also references to freely unavailable sources should be minimized. nszabolcs 09:02, 5 October 2007 (UTC)

• The author notes "This linear matrix inequality specifies a convex constraint on y." The shape of that set is not at all obvious. Secondly, does this LMI definition stand on its own? What are its origins? That is why the convexity discussion is warranted, in my opinion. --Dattorro 10:31, 5 October 2007 (UTC)

• • I prefer a clean minimalistic definition which is correct. Lengthy, technical proofs makes the article messed also new notations and concepts makes it harder to follow. The shape is not obvious, but it's important to mention that it's convex (probably a note should be added there about convexity discussion?). Anyway if the current definition is ok and the cited references contain enough detailed information then i'd leave the article this way. Those who are interested will read the references anyway. nszabolcs 16:03, 23 October 2007 (UTC)
