RE: NEW: HP 15C Collectors Edition
From studying a bit further, it turns out that this is designed behaviour, which the manual explains on p148. The matrix A is replaced by an 'LU decomposition' of itself, which is part of the solving implementation. So in reading up about that I learnt some new maths! :-)
But since the emulators I tried don't generate the LU decomposition (Retro 15C on iPhone, and https://hp15c.com) it's still worth the note in case anyone else is confused by this. |
