Hi Peter,
Sorry, I completely lost track of this thread when it came in.
Thanks for trying out the patch. I'm glad it started working for you!
Regarding your questions:
1) That defvar tells the byte-compiler that variable exists so it
doesn't throw a warning when compiling in batch-mode. You are correct
that it has no other functional value.
2) \\s_ matches symbol characters. This if you type MyVar_' it will
correctly match.
4) Yes, nconc modifies the list. You would need to make a deep copy of
electric-pairs-pairs first before modifying it. Thus, your soln of just
typing in something is good. :)
5) Use 'toggle-debug-on-error' for your first file and see what the
stack says. Hard to speculate otherwise. Run the toggle-debug command
a 2nd time to turn off debugging.
Good Luck
Eric

Hi Eric,
Thank you -- that inspired me to make electric-pair-pairs a buffer
local variable. Surprisingly (to me) electric still pairs
double-quote (") as I would expect and single-quote (') works in all
the contexts I can think of right now.
questions/comments:
1. Your `(defvar electric-pair-inhibit-predicate)` did not seem
necessary, so I removed it in my patch
2. I don't understand the `\\s_` option in your `looking-at`
argument, but kept it in, as it seems to do no harm to any of my
matlab code.
3. I added the `\\.` to `looking-at` to handle non-conjugate transpose.
4. I tried using `nconc` to add single quote to the local
`electric-pair-pairs`, but it would always change the global value as
well, so I fell back to `setq`. This is some bit of elisp that I just
don't understand.
5. I'm using emacs 28.1 now with the native-compilation on. I find
that the changes to matlab.el don't work for the first m-file opened,
but on the second one (or kill and open the first) all the electric
mods work as desired.

Hi, yes - I meant `show-paren-mode'. Not sure what I was thinking
at the time.
In the code for matlab.el, it is all about show-paren-* features
it is extending.
I poked around some more to see how to extend electric-pair-mode,
and found the defcustom `electric-pair-inhibit-predicate'. I
hacked together a little thing that prevents the mode from pairing
up a single quote after a symbol, ie - when used as transpose. The
downside is it also disables the user's selection, so not sure
what to do about that.
Anyway, I attached it as a way to brainstorm what the right
patterns are to fix the original problem.

I was wondering myself. I tend to believe that years ago there
was some
paren-mode package, but I cannot find it in my archives.
