Follow-up Comment #10, bug #34850 (project octave):
After a bit more testing it appears that it is OK
to use transpose() rather than hermitian() when the
operation is applied twice:
A = randn (4) + i * randn (4);
As = A' * A;
all (all (chol (triu (As'), 'upper')' == ...
chol (triu (As.'), 'upper').'))
ans = 1
so the attached patch works.
Salvatore, would you be able to test it too?
(file #24462)
