How to plot vertical lines?

This is the script:
x=[0:0.1:10]; x1=5;
plot(x,2*sin(x),x,5*sin(x),x,cos(x));
line([x1 x1],???????);
I would like to plot the vertical line from the top to the bottom without knowing the y-axis limits.
Thanks in advance!

x=[0:0.1:10];
x1=5;
plot(x,2*sin(x),x,5*sin(x),x,cos(x));
y1=get(gca,'ylim')
hold on
plot([x1 x1],y1)

line([x1 x1], get(gca, 'ylim'));

@Alberto Sivera if you have R2018b or later, you should really be using xline() like @Pierre Tallotte shows in his answer below.
xline(x1, 'Color', 'r', 'LineWidth', 2);

thank you, but unfortunately I have the r2017b version and i'm too lazy to update it :)

xline(x1);

simply pass in ylim for the y array:
line([x1 x1], ylim);

Not sure.
ylim() is not returning the correct y axis range limits.
That certainly is weird. I'd call tech support on this one.

If the axes is scaled, e.g. when adding new objects or for printing, using the current limits for the Y-position is fragile. You can use much larger positions and exclude the line from the list of objects, which influence the auto-scaling:
YL = get(gca, 'ylim');
YR = YL(2) - YL(1);
YL = [YL(1) - 1000 * YR, YL(2) + 1000 * YR];
line([5, 5], YL, 'YLimInclude', 'off')
'YLimInclude' in undocumented and might be removed in the future.

Does someone know how to get/download xline and yline functions? I have R2018a's version of MATLAB.
Thank you in advance.

If you dont' have xline and yline you can use line():
xl = xlim;
yl = ylim;
line([x, x], yl); % Old way of doing xline().
line(xl, [y, y]); % Old way of doing yline().
