plot a vertical line in matlab

To plot a vertical line in Matlab, you can use the xline function. This function creates a vertical line on a plot at a specified x-value. Here is an example of how to use xline:

main.m
x = 5;
plot(1:10, rand(1,10));  % plot some data
hold on;
xline(x);  % plot vertical line at x=5
97 chars
5 lines

In this example, a vertical line is plotted at x=5. The hold on command is used to prevent the plot from being overwritten by the xline plot command. You can customize the appearance of the line by specifying additional input arguments to the xline function.
