Hello, I'm MelbourneStar. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Singular value decomposition— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. —MelbourneStar ☆ talk 12:44, 28 May 2015 (UTC)
