I noticed in the latest j701 updates, all the demo files, as well as the
client/server are zeroed out:
-rw-r--r-- 1 scott scott 0 Feb 1 20:03 jdbclient.ijs
-rw-r--r-- 1 scott scott 39446 Dec 4 16:50 jdb.ijs
-rw-r--r-- 1 scott scott 0 Feb 1 20:03 jdbserver.ijs
-rw-r--r-- 1 scott scott
Just checked mine: same here, in a 32-bit Windows 7 environment.

Here's a related expression.
4 4 4 4 #."1 0 i. 4
0 85 170 255
I like how this relates array structure to polynomial structure.

Not sure why this had happened, files in svn are ok. Any ways,
the version of jdb has been updated.

In addition to the diagonal expressions in the phrases,
http://www.jsoftware.com/docs/help701/phrases/special_matrices.htm
is a hook for diagonal.
rank =: #@:$
diagonal =: |:~ <@:i.@:rank
diagonal i. 3 3
0 4 8
diagonal i. 3 3 3
0 13 26
diagonal i.3 3 3 3
0 40 80

Let's do this in classical APL style.
Fix the number of rows and columns in your network.
numcols =: 4
numrows

This is a nice trick to create the list of edges. However, it doesn't
work for a non-square matrix. For example, (pairs i. 3 4) will
Thanks for the quick fix!
I looked for other empty files in the addons directory, but I guess files only
disappear when you need them. Probably, they were hanging out with my keys and
Schroedinger's cat.

You need to regenerate rows and cols to match the matrix size you are
working with:
'row col'=. |:3 4 #:,i.3 4
pairs =: [: ,/ [: (2 ,/\ ])"1 (, |:)
pairs i. 3 3

4 7
2 5
5 8
