pdist() with the 'cityblock' argument should do the trick.

I cant seem to get it to work. What I have is a group of 8 points and want to gather a distance matrix for the manhattan distance between them, below is the script i am trying to use, any help?
x = [0, 6, 6, 6, 7, 7, 8, 8];
y = [0, 0, 2, -2, 2, -2, 2, -2];
A= plot(x,y,'bo')
axis([-2,10,-5,5])
labels={'exit','terminal','Gate1','Gate2','Gate3', 'Gate4','Gate 5','Gate6',};
text (x-0.5,y-1,labels,'bottom')
title(' Airport Layout')
D = pdist(A,'cityblock')

You are trying to get the distance of a graphic object handle (in your case a line).
Perhaps this is what you meant:
x = [0, 6, 6, 6, 7, 7, 8, 8];
y = [0, 0, 2, -2, 2, -2, 2, -2];
D = pdist([x',y'],'cityblock')
Please read the documentation. Also, please accept the answer that best solves your problem.
