Update of bug #44722 (project octave):
Status: None => Ready For Test
_______________________________________________________
Follow-up Comment #8:
The zero tolerance was useful in catching that we were using a different
algorithm between linsolve and the expected result in assert. I've re-written
linsolve to not perform the transpose of A in Octave, and instead forward the
transpose flag to BLAS. This is what we already do if you write
A' \ b
at the prompt. This yields a 40% speed improvement in linsolve and there
shouldn't be a BIST failure anymore because linsolve and the interpreter are
using the same algorithm.
A changeset for test is attached. Please try it and if it works I'll commit
it before the 4.0 release.
