"If the first element of the first row of every row pair is positive at this point, then the system is stable." Needs clarification, what is a row pair?

Moreover, I don't think that it is correct. Actually, the system is stable if the absolute value of the first element of each odd-numbered row is greater than the absolute value of the last non-zero element in the same row. The Italian version of this article is good I think. Even the construction of the table is a bit more complicated in the English version. Maybe, it should be clearer to use determinants of 2x2 matrices. Ciano bill (talk) 22:23, 8 May 2008 (UTC)
