How to do distance formula

Im trying to find the distance between 2 points on a truss and I have the length and the x and y of the nodes on the truss but what code in matlab would make this work.

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];

[KSSV]

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