Looping matrix differences for every iterations

I have this scenario

A=[6;7;8] W=[3;9;1] d=|Ai-W| for each iterations take one value from A subtract with every value in W

1 iteration

d=

6-3
6-9
6-1

Like this for another iteration

Answer 1

[Andrei Bobrov]

d = bsxfun(@minus,A(:)',W(:));

[Anusha]

not like this sir..

for first iteration d=

   3
  -3
   5

for second iteration d1=

 4
-2
 6

d2=

 5
 -1
 7

each differences A take one by one value

@Anusha: Please read Andrei's suggestion again and think twice, why he prefers this method. It is a bda programming practice to insert an index in the name of a variable. His approach uses and index as index (!):

d(:, 1), d(:, 2), d(:, 3)

This is much more useful and efficient. You can e.g. expand the problem easily to millions of elements.
