Hi all Here is a question which has been puzzling me for a few days now. Any help would be greatly appreciated. I think that I need to put all the terms in the inequality on one side, then factorise and consider what it means to be a positive definite matrix but I keep tying myself in knots! Thanks=) Last edited by ChristineJW; March 18th, 2017 at 04:16 PM.
