Distance betwen 3d points

So basically I have an aray of points, of length 14, with coordinates x, y and z. And I have an array of connections, defining the connections of the points I want to calculate the distance. How would you do it? I have tried to do it with nested for loops but can't seem to get the hang of it.

something like this

%  Connectivity
Con = [1 2; 3 4; 5 6; 7 8; 9 10; 11 12; 13 14; 1 3; 3 5; 5 7; 7 9; 9 11; 11 13; 2 4; 4 6; 6 8; 8 10; 10 12; 12 14; 2 3; 4 5; 6 7; 7 10; 9 12; 11 14];
%  Nodal Coordinates
Coord = [0 2500 0; 0 3750 0; 1340 3040 0; 1340 4290 0; 2670 3530 0; 2670 4780 0; 4000 3700 0; 4000 4950 0; 5330 3530 0; 5330 4780 0; 6660 3040 0; 6660 4290 0; 8000 2500 0; 8000 3750 0];

If you have the statistics toolbox you can use pdist2.

I can't use any other toolboxes

How about sqrt() or norm()?

wait sorry, we can use any toolboxes, so pdist, sqrt or norm can be used
