RE: About LU factorization
Have you tried reversing the decomposition to see if you get the original matrix back?
Looks like the prime swapped the second and third rows during the factorisation which changes the later results. Earlier HP calculators use the Doolittle decomposition with partial pivots, I'd be surprised if the prime didn't do something similar. - Pauli |
