Talk:Underdetermined system

There are some issue. I have just modified Tychonof regularization since it talk about overdetermined system, but it is not true: Tychonof regularization is useful when the unknowns are more then the equations, i.e. an underdetermined system. However the examples in this page are for overdetermined system against the definition!!!

I confirm the previous comment. The examples are wrong and misleading, since they describe and OVERdetermined system. — Preceding unsigned comment added by Federico.giorgi (talk • contribs) 15:09, 20 January 2011 (UTC)


 * So I am the 3rd confirmer :) seems like most of the article is a copy of Overdetermined system. Don't know, why nobody changed this thing yet. Maybe it's better to cancel the hole article, hence it's quite misleading. --WissensDürster (talk) 09:16, 24 January 2011 (UTC)


 * Yes, I also confirm that the examples are wrongly copied and very misleading. Perhaps someone who understands this well could repair the article or delete it if It's all wrong. Neználek (talk) 19:41, 21 April 2011 (UTC)
