matlab plot vertical line

To plot a vertical line in MATLAB, you can use the xline function. Here's an example:

x = 5; % x-coordinate of the vertical line
xline(x);

This code will plot a vertical line at x = 5. You can customize the appearance of the line by specifying additional arguments to the xline function, such as line color, line style, and line width. For more information, you can refer to the MATLAB documentation on the xline function [[SOURCE 1]].

I hope this helps! Let me know if you have any further questions.
