Follow-up Comment #12, bug #48085 (project octave): I think the size of the benchmark is too small. Try to increase both numbers by factor of 10. (Num=10000; ItNum=100;) octave-cli (4.0.1 -- as provided by Fedora 24) octave:1> lutest_v Simple left division Elapsed time is 13.3167 seconds. LU decomposition Elapsed time is 1.77494 seconds. same octave (with gui): >> lutest_v Simple left division Elapsed time is 12.9441 seconds. LU decomposition Elapsed time is 1.8458 seconds. same octave ( --no-gui): >> lutest_v Simple left division Elapsed time is 13.6711 seconds. LU decomposition Elapsed time is 1.78795 seconds. octave 4.1.0+ (SELF-COMPILED): >> lutest_v Simple left division Elapsed time is 13.1303 seconds. LU decomposition Elapsed time is 1.77669 seconds.
