Bug report

[marethyu]

I am a user of G1 HP Prime with firmware version 2.1.14730.

I discovered that when you try to compute SVD of the matrix [[1, 1], [0, 0]] in CAS mode, HP Prime crashes for some reason.

You could update to 2.2 and try again.

Confirmed behaviour for HP Prime G1 (both in CAS and HOME modes)

Software Version: 2.2
Hardware Version: C

Details
Software Build Date: 2024-09-01
Software Revision: 15157
Versión de CAS: 1.5.0
Versión de MicroPython: 1.9.4
Sistema Operativo: V0.050.640

However, HP Prime Windows emulator (CAS mode) shows a warning message before giving an answer (which I think is correct). In HOME mode, no warning message appears and the answer is the same as CAS mode.

Versión de software: 2.1.14730 (2023-04-13)
Versión de hardware: Emu
Versión de CAS: 1.5.0

Thank you for the bug report. The detailed description is appreciated. I’ve managed to reproduce the issue (on both 2.2 and the current internal beta) and have created a ticket for this in the bug tracker.

It seems that displaying the message that the matrix is ill-conditionned crashes the G1. At least disabling the message fixes the crash.
