Hello, I'm CFA. I noticed that you added or changed content in an article, Simulink, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. C F A  💬  20:11, 18 July 2024 (UTC)

Please do not add promotional material to Wikipedia. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you. MrOllie (talk) 18:46, 19 July 2024 (UTC)
