Talk:Inverse element
From Wikipedia, the free encyclopedia
[edit] left/right matrix inverse
I think the phrase
- If the determinant of M is zero, it is impossible for it to have a one-sided inverse; therefore a left inverse or right inverse implies the existence of the other one.
is redundant, and not very clear, (IMHO):
- why det=0 => no one-sided inverse ?
- why "no one-sided inverse" => "l/r inverse implies existence of the other" ?
- more specifically, why is a left inverse matrix also is a right inverse ?
But as I already did some "cutting", I'll leave it for the moment... MFH 15:17, 5 Apr 2005 (UTC)
