Hi All,
I am trying to generate a matrix that looks like this:

0 1 2 3 4 5
1 0 1 2 3 4
2 1 0 1 2 3
3 2 1 0 1 2
4 3 2 1 0 1
5 4 3 2 1 0

Can anyone think of a way to generate this matrix without a For loop? Thanks!

Was not intentional. Not even sure how it happened. But thanks for the reply on the other post.
