Attempted to access x(5); index out of bounds because numel(x)=4.

could you please to help me , i have this error when i tried to run this code which calculate distance between two points groups
x = [2,3,4,5];
y = [4,4,5,4];
s_x = size(x);
d2 = (s_x(1,2));
d = zeros(1,4)
for ii=1:1:d2
d(ii) = sqrt((x(ii+1)-x(ii))^2+(y(ii+1)-y(ii))^2);
end
any one have any idea about solution?

It looks like you're trying to do this:
x = [2,3,4,5];
y = [4,4,5,4];
deltax = diff(x)
deltay = diff(y)
distances = sqrt(deltax .^2 + deltay .^2)

The error is caused by ii iterating from 1 to 4, but you use ii+1 (=5 at last iteration) as an index into the x and y vectors which are only of length 4. For your example, what would you like the desired output to be? I.e., what would the desired values of d be for your example?
