Example: ... 0.1 0.2 6 0.1 7 8 ... In the first row you get two values meeting your condition and the function "find" gives two entries with the same index i...

He makes these claims for it: "The Lomb-Scargle periodogram is a common tool in the frequency analysis of unequally spaced data equivalent to least-squares fitting of sine waves. We give an analytic solution for the generalisation to a full sine wave fit, including an offset and weights ($\chi^{2}$ fitting). Compared to the Lomb-Scargle periodogram, the generalisation is superior as it provides more accurate frequencies, is less susceptible to aliasing, and gives a much better determination of the spectral intensity. Only a few modifications are required for the computation and the computational effort is similar. Our approach brings together several related methods that can be found in the literature, viz. the date-compensated discrete Fourier transform, the floating-mean periodogram, and the "spectral significance" estimator used in the SigSpec program, for which we point out some equivalences."

Search the mailing list archives for previous examples, in some sense, "vectorization quizzes" are a sort of "game" we some times like to play among Octave programmers to test our abilities. Code vectorization can some times improve execution speed by orders of magnitude and, even when it does not lead to dramatic optimization, many Octave programmers find vectorized code easier to read and more "elegant". no need to show the full code, a stripped down example is often good enough to try and check how much improvement you can get from vectorization. this particular example looks like it can probably be reduced to a one-liner I'll give it a try later, but it would be more interesting if you could propose something closer to the "real thing". Of course the JIT is a great improvement, which has been in great demand for quite a long time among Octave users, I also am looking forward with great excitement at the outcome of this project. I don't see your point here, what do you mean by "manipulating manually"? c. </pre> c. 2012-05-24T11:41:33 http://permalink.gmane.org/gmane.comp.gnu.octave.general/41685 <pre> It still remains to be seen what sort of speedup JIT compilation will give us on real code, hopefully it will help in your case.

However there were problems with the older version of optim too, but they seemed fixable. First there appears to be an extraneous "end" statement on line 109 of brent_line_min.m (right before "nev++"). That or whatever it ended is missing. I just commented it out. Second, polyconf.m needs to have an "end" added to the end of the confidence() function (the very end of the file) otherwise 'pkg install' complains that "inconsistent function endings -- if one function is explicitly ended, so must all the others". Fixing those two things allowed me to install optim-1.0.6 - Octave complains about core library functions being shadowed, but what I need working seems to be so...
