Hello, I'm Gilliam. I wanted to let you know that one or more of your recent contributions to State-space representation have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks. – Gilliam (talk) 06:14, 17 April 2017 (UTC)
