## problem with column specification in matrices

 From: Mike Miller Subject: problem with column specification in matrices Date: Thu, 31 Oct 2002 13:07:22 -0600 (CST)

```What's the deal with this?  In command 3, you can see that octave messes
up when I do not include a comma between columns of the matrix.  A comma
seems not to be required, so this seems like a bug.  It does it at least
under 2.1.36.
