Counterproductive edit on Rotation matrix
Hi, i reverted your inappropriate "Warning" message stuck at the top of the rotation matrix article. Beyond being wrong, to the point of dyslexic confusion, such comments belong to the discussion of the article in the Talk page, and not in the article itself. You abused the article with graffiti, as though it is an open whiteboard inviting every passer-by's comments. Cuzkatzimhut (talk) 15:38, 15 April 2015 (UTC)
