Plotting a line x=constant

Hi,

What is a good way to plot a straight line parallel to y-axis for a particular x value?

I've used this code but the line is dotted

x=3;
y=0:0.001:0.3; %How much is long
plot(x, y, 'LineWidth', 10) % but is not large enough

This is what i did and the result:

clear 
clc
close all
x=3;
y=0:0.001:0.3; %How much is long
plot(x, y, 'LineWidth', 10) % but is not large enough

Another option:

line([x x],[y(1) y(end)],'LineWidth',10)

Answer 2

You can use xline command

Answer 3

[Paulo Silva]

plot(x*ones(size(y)), y, 'LineWidth', 10)

or

plot(x*ones(1,size(y,2)), y, 'LineWidth', 10)

Answer 4

xline(3);
