[julia-users] Re: FFT speed much slower than Octave

For a fair comparison, the Julia function rfft() should be compared with the Octave function fft2(). Both do a 2-D transform. I don't see any significant differences between Julia (with 2 threads) and Octave. Perhaps the discussion can be continued on github: https://github.com/JuliaLang/julia/

Did you try: sudo add-apt-repository ppa:staticfloat/juliareleases sudo add-apt-repository ppa:staticfloat/julia-deps sudo apt-get update sudo apt-get install julia You need to have the correct ppa enabled! Uwe On Friday, July 15, 2016 at 3:49:04 PM UTC+2, Ahmed Mazari wrote: > > How to i

Re: [julia-users] Re: How to install 0.4.5 on Ubuntu?

Well, the ppa is up-to-date and works well. On Ubuntu a ppa is (nearly) always better than generic binaries, because the package manager can be used to keep Julia up-to-date. Only if a ppa is not maintained generic binaries are an alternative. Uwe Am 15.07.2016 um 19:37 schrieb Tony Kelman: > T

Re: [julia-users] Re: How to install 0.4.5 on Ubuntu?

Well, you can always pin a version. See: https://help.ubuntu.com/community/PinningHowto For me, using Ubuntu packages is the easiest way to go, in particular if I have to explain students how to install Julia. Uwe On Friday, July 15, 2016 at 10:16:59 PM UTC+2, Tony Kelman wrote: > > The ppa i

Hello, in the issues on github I see a lot that refer to gc frames. What is a gc frame? I know how garbage collection works in general, but I don't understand the meaning of gc frames in the context of Julia. Could someone explain: - What they are used for? - When they need to be created? - If th

[julia-users] Re: new installation of julia

Is there a reason, why you want to compile Julia yourself? It might be easier to use a precompiled version, that you can download from http://julialang.org/downloads/ . ln -s creates a symbolic link to the executable, such that is in the search path. This is the way to go on Linux, but I don't

The informations, that you give are not precise enough. Which Windows version do you have? How do you launch julia? Are you sure, that you do not have to versions of julia on your computer? On Linux, for me the following was sufficient to upgrade julia 0.4 to 0.4.7-pre+3: git pull git checkout
