Follow-up Comment #21, bug #53140 (project octave):
I see something strange (to me): if I declare
OCTAVE_LOCAL_BUFFER (double, Bx, b_nr);
OCTAVE_LOCAL_BUFFER (double, Xx, b_nr);
OCTAVE_LOCAL_BUFFER (double, W, b_nr);
OCTAVE_LOCAL_BUFFER (octave_idx_type, Wi, b_nr);
I do not see any improvement. On the other hand, with
OCTAVE_LOCAL_BUFFER (double, Bx, b_nr);
OCTAVE_LOCAL_BUFFER (double, W, b_nr);
OCTAVE_LOCAL_BUFFER (octave_idx_type, Wi, b_nr);
OCTAVE_LOCAL_BUFFER (double, Xx, b_nr);
I see the reduction from about 55 seconds to 40. Does it make sense?
