I see now what went wrong. When the original author posted his code he forgot about the support code. Hence the error. With the code restored/rewritten with grateful thanks, we now have the expected result.With many, many thanks. What a story to share at the next Mathsjam next week.In lines 19 to 33 of the original code, there is mention of the king, queen, bishop and rook. Can the same code be used for that? How do I tell it to do the king for instance?SimonOn Mon, 11 Feb 2019 at 22:25, Doug Stewart <address@hidden> wrote:On Mon, Feb 11, 2019 at 5:04 PM SimonAllen <address@hidden> wrote:The error I am seeing is this

What I suddenly realised is that spiralknightsmove calls spiralNumbers
I had it in my head that the subroutine had to be within the main code. It
should work provided spiralknightsmove can see spiralNumbers.
So what I have done is to use 'pwd' and that tells me where Octave is
looking. In my case it is
>> pwd
ans = /Users/Simon
Next I accessed both files in Dropbox. I used direct download and then
moved both files to /Users/Simon
Next to be sure I typed
>> ls
spiralNumbers.m
spiralknightsmove.m
There is a lot of other stuff there folders and files but both of these
files are there
Next I opened spiralknightsmove.m in Octave and hit Run. That gives the
error above. So Octave is not seeing the other file even though it is in
the same path. I am not sure why it is still not seeing it.
I am on a Mac but that should not make any difference or is it a file
permission issue?
