Hi all,I am new to matlab. I am trying to implement an intersecting roads but getting this error "vectors must be the same length". Could someone help me in this code? Thanks in advance...
clc
clear all
rw=10;
roadcenters1=[0 25;50 25];
roadcenters2=[0 -25;0 25];
width=10;
plot(width,roadcenters1,roadcenters2);

Read the documentation (just type doc plot). You will learn that this is not the syntax you're looking for. If you want a plotted line to have a certain width, use the 'LineWidth' property.

If I do not write width in plot(width,roadcenters1,roadcenters2) it simply plot two intersecting lines. Could you provide me the code to draw two intersecting roads?

You can use plot to plot lines of a few different kinds, but they stay lines. If you want to plot two pairs of thick lines, use the code below.
roadcenters1=[0 25;50 25];
roadcenters2=[0 -25;0 25];
width=10;
plot(roadcenters1,'b','LineWidth',width)
hold on
plot(roadcenters2,'r','LineWidth',width)
