Lets suppoese i have the points as shown by B. For example, P1(1,1,2 ), P2(1,2,3 ) etc as shown by B. I want to measure the shortest distance among these points.
x = B(:,1), y =B(:,2) and z = B(:,3).
Thanks in advance for support from community members. Regards!
B =
1 1 3
1 2 3
2 3 1
2 3 2
3 1 1
3 3 1
3 3 2

Thanks Sudkhakr Shinde and KSSV for your kind reply. Actually, we can use 'norm' function to measure distance between two points. But i want to measure the distance among all the points, then i want to pick the minimum distance. Please any help. Regards

B = randi([-10 10],5,3); % just some random numbers
minimum = sqrt(sum((B(1,:)- B(2,:)).^2));
for i = 1 : size(B,1)-1
for j = i+1 : size(B,1)
minimum = min(minimum,sqrt(sum((B(i,:)- B(j,:)).^2)));
end
end
disp(minimum)
