If(x1,y1) and (X2,y2) are two points. To get the distance use the formula:
d = sqtrt((x2-x1)^2+(y2-y1)^2) ;

but what if its an array of points
ie
X = [0 0
1 0
2 0
2 1
1 1
0 1
];
that are connected at points
y = [1 2
2 3
3 4
4 5
5 6
6 1
2 4
3 5
1 5
2 6];

d = sqrt((x(:,2)-x(:,1)).^2+(y(:,2)-y(:,1)).^2) ;
