Follow-up Comment #1, bug #53140 (project octave):
I just tested the matrix with the development version of Octave on Linux:
octave:3> lu_test
Elapsed time is 41.4186 seconds.
octave:4> linsolve_test
Elapsed time is 91.4311 seconds.
The lu_test script uses your second code. Clearly this is a big matrix, but I
don't see anything like 10 hours.
I'll see if I can start a virtual machine running Windows XP and check the
result there.
