A short followup ...
I forgot to mention in my last post that it seems that one needs to
hit the enter twice for 1; ..., but not for the very last (the
nn-th) element. As I was thinking whether to bother the list with
this little detail, I went back to my Xmaxima window to try this one
more time. This time I typed:
(c12) entermatrix(4,4); <enter>
However, when I hit the enter, instead of the cursor being moved
to the new line, I got
entermatrix(4,4);entermatrix(4,4);
I then hit enter several more times, and got:
(C12) entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);entermatrix(4,4);
entermatrix(4,4);
I am not sure if I used Ctrl-G (or something else) to interrupt
this, but then (c13) entermatrix(4,4);
1; <enter><enter> ...
worked fine (only one <enter> needed for the last step).
