Thread: LLL in GP/Pari View Single Post

First, the wikipedia example: https://en.wikipedia.org/wiki/Lenstr...tion_algorithm Code: (20:32) gp > qflll([1,-1,3;1,0,5;1,2,6]) %50 = [-4 5 0] [-1 1 1] [ 1 -1 0] Second, the matlab example: http://www.mathworks.com/help/symboloddslotic/mupad_ref/lllint.html Code: (20:32) gp > qflll([1, 2, 3;4, 5, 6]) %51 = [-1 4] [ 1 -3] [ 0 0] As you can see, both results are incorrect. What am I doing wrong? Last fiddled with by paul0 on 2015-11-17 at 12:35
