Distance between elements of matrix

I have a single line matrix in Matlab

 U= -25.2465   -5.1193   44.1124  -18.1332    9.2715   43.7203  -48.6050.

What i want to find is the distance between consecutive elements..

For ex:- first selecting the first point -25.2465 and finding the distance with all other points..In the same way simultaneously selecting -5.1193,44.1124..and so on.

The output i intend to get is a distance matrix

0                (-5.11+25.24)   ...   ...  ... ... ...
(25.324-5.1)            0
(25.24+44.11)    (-5.11+44.93)   ...   ...  ... ...  ...
(25.24-18.13)        ...
(25.24+9.71)         ...
...

How should i write this code

Answer 1

[Andrei Bobrov]

out = abs(bsxfun(@minus,U,U'));

or use function dist from Neural Network Toolbox

out = dist(U);

Answer 2

[Azzi Abdelmalek]

n=numel(A)
B=-diff(A(fullfact([n n]))')'
