On the other hand, entering a real matrix ((1; 1); (1; 1)) and a second (complex) matrix ((1; 1); (1; i)) and dividing the first by the second results in
This is the resulting matrix as it should look (compare Tom's post). Which release did you use?

Re: 43S News
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.

Re: 43S News
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.PierreMengisen wrote: ↑Fri Aug 20, 2021 9:14 amOther example of that issue :

Re: 43S News
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.

Re: 43S News
Does anybody else observe a similar problem?

The way it should look depends on how you do it.Walter wrote: ↑Thu Aug 19, 2021 10:25 pm@Pierre: Point taken.

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

Re: 43S News
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
