Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
Bon, alors je remplace l'item 5.8 par un item bug en attendant
Je viens de mettre a jour, avec une correction de bug de portage qui empechait de calculer des exponentielles de matrice du type exp(a*t), en fait le portage sur TI n'a pas l'air d'aimer l'algorithme de calcul modulaire de PGCD, je le desactive pour l'instant (en attendant que je passe sur newlib).

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
Is there an english version of the guide?
archives_voir.php?id=78777
I'd love to have a TNS of a PDF or something like this that I can read on my calculator.
If anyone has info, please let me know

There is nothing specific to khicas in English, but a large part of Xcas documentation http://www-fourier.ujf-grenoble.fr/~parisse/giac/doc/en/cascmd_en/cascmd_en.html applies.

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
I found two bugs:
-"x=5d" -> "(x ing errors are becoming damaging. 5 * d)" (WTF)
-"1°" -> Crash (has to be computed twice, sometimes)
Tested on 3.9.1 CAS CX.
-"x=5d" -> "(x ing errors are becoming damaging. 5 * d)" (WTF)

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
Very strange error message, I could only find the string in solve.cc in cobyla code (optimization code) but how could it be called? No idea.
The crash is certainly a parse problem, perhaps unrecognized utf8 sequence (returns 0 under Xcas).

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
I'm using KhiCAS on OS 3.9.1, on a TI-nspire CX (non-CAS), and am having some issues when I exit KhiCAS.
The first time I start and exit KhiCAS, everything goes just fine. However, if I go to open up KhiCAS and close it again, my calculator crashes. I have no idea what is causing it.
Also, after KhiCAS starts and I do a calculation, the status bar (is that what its called in this instance?) disappears until I press one of the arrow keys. Its not too much of an issue, but it bugs me.

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
I can not reproduce a crash with a few commands (factor(x^4-1) then normal((x+1)^6)). Perhaps it's OS 3.9 (I'm on OS 3.6) ?

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
Probably. I just assumed it would work fine because it looks like Vogtinator was using it on OS 3.9 as well. Is there any way I could get some data about what is causing the crashes? Perhaps some sort of log file?
Edit: It also looks like you may have misunderstood my other post. The crashes occur the second time I open and close KhiCAS.
Another edit: I'll try to make a video of the missing status bar thing tomorrow as well

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
I tried to open/close twice the same document with or without ON/OFF cycle, but did not see any crash. I get sometimes crashes if I download khicas.tns from the PC several times (and of course also sometimes because of a bug after running a command, but this happens consistantly).

Re: KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire
I made a video demonstrating the crash and the missing status bar, in case that helps at all:
