This is the resulting matrix as it should look (compare Tom's post). 8-) Which release did you use?

I am using WP43S Windows Parallels Desktop 17
I installed GTK3 and WP43S.EXE using CrossOver into a bottle of its own and it works on my 2019 MBP with Big Sur, with no issues.

A={(1;1) (1;1)} B={(1;1) (1;i)}
A/B => complet freeze :oops:
I think I use the last version

And here is an example that works correctly:

This matrix divided by itself gives the unit matrix, the one is right.

Also this example works here, resulting in (rounded)

I'd recommend removing (rm) backup.bin and trying again.

No backup.bin in the library.

The problem must lie elsewhere.

The strange thing is that it works in some cases and not in others.
The problem is to find out in which case there is a wp43s.exe crash as I lose track of the data used.

Does anybody else observe a similar problem?

(Feel free to report other problems as well, of course. 8-) )

The way it should look depends on how you do it.

inv(b) * a gives [[1 1][0 0]]

a * inv(b) gives [[1 0][1 0]]

The HP 50g, HP Prime and Casio fx-CG500 do it the first way and it looks like the 43S does it the second way.

A new indication: with the version wp43s_jm.exe it works as agreed.
What is the difference between wp43s.exe and wp43s_jm.exe?
(the first one is 2'034'348 bytes while the second one is 2'075'070 bytes)

It is also interesting that this division works with the previous version wp43s-windows-0.20-2.5 :?:
