Hi Alexander,
I am rather new to APL and had similar issues.
There are various paths to get APL symbols running. I didn't want to
spend a modifier key (CTRL/META/SUPER/...) for apl. So I went the path
to utilize .XCompose, see attached example. So I press f.e. '.'(period)
and than follow with '$'
Hi Blake, hi Jin,
I'm afraid this assumes that the X server already has an idea of what an APL
layout would look like, in which case "setxkbmap us,apl" should also work.
Unfortunately this is apparently not the case with my setup. The man page for
xkeyboard-config(7) does not mention an apl lay

Hi Alexander,
keyboard layouts are a moving target.
When I started GNU APL I used xmodmap which was the most reasonable
way
to do it at that time. At some point in time (after a system
upgrade from Mint 18 to Mint 19)
xmodmap stopped workin
I'd suggest taking look at the Emacs mode. It will only provide the ability
to enter APL symbols in Emacs but that's usually acceptable.
It does allow you to avoid messing with X keymaps.

Thank you. The Cholesky decomposition is related but not what I'm
implementing at the moment. However this will likely be useful in the
future.
Even the name "QR algorithm" seems to be something of a misnomer. From the
wikipedia page:
" in the modern implicit version of the procedure no QR decomp
Hi,
I assumed that same technique can be used for QR algorithm. check the
algorithm section.

I believe I've figured out what was confusing me. The notation used in
Golub/Van Loan is referred to as "block matrix notation".
If only there was some sort of... universal math notation that didn't rely
on per-topic experience and context clues... ;)

It looks like the Cholesky decomposition article uses block matrix
notation, so it looks like it will be useful, just not for the reason I was
expecting. Thank you Ala'a.
