Follow-up Comment #18, bug #48085 (project octave): Dmitiri You are right. And thanks for your correcting my misleading. The for 4.1.0+ binaries, the refblas is default unlike 4.0.x. I replaced libblas by libopenblas. The bentimark results are Simple left division Elapsed time is 1.9463 seconds. LU decomposition c=P*B Elapsed time is 0.038023 seconds. y=L\c Elapsed time is 0.656441 seconds. x=U\y Elapsed time is 0.647431 seconds. The above are almost the same as those on 4.0.2 (x64). Sorry for the noise. So please close this tracker. However, LU decomposition does not have merit on octave. But this is not a topic that are discussed here. I will raise post in the octave ML. Anyway please close this post. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?48085> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
