Looping matrix differences for every iterations
显示 更早的评论
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

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

@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.
