All eigenvalues ... entries ... have to be zero: the eigenvalues can also be complex. -- looxix 00:18 Mar 12, 2003 (UTC)

In particular, in the matrix

which the article gives as an example, the eignevalues are not zero. Nor are they real; they are imaginary. And the determinant of that matrix is not zero. Michael Hardy 00:26 Mar 12, 2003 (UTC)

I see that there is already a page titled skew-symmetric matrix, and that it redirects to symmetric matrix. Perhaps we should just redirect this page to there, since this articles is so very short, and we don't need a page for every conceivable topic that might fit neatly into another article.

I broke this material out of symmetric matrix for the opposite reason -- someone following a link to find out about Skew-symmetric matrix should't have to wade through a page or so on symmetric matrix. Furthermore, they may think they're reached the wrong place, because there's no indication at the start of the article that they havent (and putting one in, I think, will make it read badly). There's nothing inherently wrong with a short article -- Tarquin 10:03 Mar 12, 2003 (UTC)
