Find the source of output in Command window

The code I wrote was quite lengthy. There is a number "2" that keep appearing during iterations. I think I forgot to type ";" somewhere. I am wondering if there is a command that can help me find the source of the problem.

You probably have to write a custom script to search all your code for the semicolon error. See this Q&A which provides a starting point for doing this.

The other way is the use the Matlab Editor, side bar on the right that shows a orange bar for warning/suggestions. An orange line will appear if you forgot to add semicolon. Maybe the line you need to fix is highlighted in orange. Hopefully there isn't too many orange lines...

Another option is to call mlint directly. This will give the same warnings as these orange/yellow (they look orange to me!) lines but in a text form.

Nice! Seems like mlint is now checkcode https://www.mathworks.com/help/matlab/ref/checkcode.html

The warnings are indeed orange. I had to create a lot of mistakes to see the orange hue.
