Download Octave For Fedora ~UPD~

Packages of Octave packages have their own naming scheme. They should take into account the upstream name of the package. This makes a package name format of octave-$NAME. When in doubt, use the name of the module that you type to import it in octave.

Limitations in the pkg function of octave (pkg.m) means that versioning of octave packages requires that the package version must have a MAJOR.MINOR.MICRO format. Failing to use this format results in octave not recognising binary package components in %prefix/libexec.

Any way to tell the configure tool for octave about this? (the obvious thing of adding another CPPFLAG/LDFLAG does not work). I'm assuming I'll encounter more such issues along the way, so any generic help/hint is greatly appreciated.

Which installed on my computer the latest version of octave, 3.6.2. It works great, however when you multiply two huge matrices together it bogs down the one CPU that octave uses. It would be nice if the matrix multiplication utilizes all of the cores, since in this case the CPU is obviously the bottleneck.

Octave itself is a single-thread application that runs on one core. You can get octave to use some libraries like ATLAS which utilize multiple cores. So while Octave only uses one core, when you encounter a heavy operation, octave calls functions in ATLAS that utilize many CPU's.

I was able to do this. First compile 'ATLAS' from source code and make it available to your system so that octave can find it and use those library functions. ATLAS tunes itself to your system and number of cores. When you install octave from source and specify ATLAS, it uses it, so when octave does a heavy operation like a huge matrix multiplication, ATLAS decides how many cpu's to use.

This Atlas software uses a lot of overhead to split your octave program into multiple threads. Sure it goes much faster if all you are doing is huge matrix multiplications, but most commands can't be multi-threaded by atlas. If extracting every bit of processing power/speed out of your cores is top priority then you'll have much better luck just writing your program to be run in parallel with itself. (Split your program into 8 equivalent programs that work on 1/8th of the problem and run them all simultaneously, when all are done, reassemble the results).

Atlas helps a single threaded octave program behave a little bit more like a multi-threaded app but it is no silver bullet. Atlas won't make your single threaded Octave program max out your 2,4,6,8 core processor. You'll notice a performance boost, but the boost will leave you searching for a better way to use all the processor. The answer is writing your program to run in parallel with itself, and this takes a lot of programming skill.

The search service can find package by either name (apache),provides(webserver), absolute file names (/usr/bin/apache),binaries (gprof) or shared libraries (libXm.so.2) instandard path. It does not support multiple arguments yet... The System and Arch are optional added filters, for exampleSystem could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system. System Arch RPM resource octaveOctave is a high level programming language. It is designed for thesolution of numeric problems.This package contains the graphical user interface.

The solution would be to install the miscellaneous packages yourself. Note, that you will probably need to run octave as root for the installation, or give your user write permissions to /opt/octave3.8/share ...

Well, most important is that you could achieve what you wanted - "how to install octave for RHEL8.3" - right ? :)

That's what you'd asked for, and I provided you with the solution. There are thousands of applications out there,

so "some guide about the packages that require separate repositories at the Red Hat home/support page" isn't

exactly something that Red Hat would want to realize - as they do focus on their own products in the first place.

The answer is to modify the properties using the 'alacarte' menu editor. Find the GNU Octave entry in this editor and change the command to '/usr/bin/octave --force-gui' in the properties window. Thereafter tick off the box which asks the program to be run in the terminal. Voila!

I launched octave using "/usr/bin/octave --force-gui". This started the gui and dropped an icon on the dock for the gui. I right clicked this new icon and locked it to the dock. Then unlocked the defult Octave icon.

This has been reported before here: fedora 29 install RStudio desktop failed

An rstdudio employee replies there that " it's unlikely anyone else is running with a similar environment", but I can assure we are running hundreds of workstations with this setup.

Since I have switched to Wayland, I have been running Octave with LIBGL_ALWAYS_SOFTWARE=Yes whenever I need to plot something. I think jwe wants to add some logic to the octave wrapper executable so it automatically sets this environment variable when needed.

I also see the problem with qt5 and can confirm that resizing the window makes the plot appear.

If I run Octave, attach gdb to the octave-gui process, set a breakpoint in the QtHandles::Container::resizeEvent function and then execute "sombrero" at the octave prompt, execution stops in the resizeEvent function and the figure is properly displayed when I continue execution. If I delete the breakpoint or type "continue" for gdb prior to executing "sombrero", then the plot doesn't appear properly.

To me, this suggests some kind of timing or threading issue. And if I make the attached change (inserting a delay in the QtHandles::Container::resizeEvent function), it seems the plot will appear correctly given a sufficient delay. On my system, a delay of 0.2 seconds appears to be sufficient to make the plot always appear correctly. With a smaller delay the plot is sometimes correct and sometimes not. Oddly, it seems to fail more often if the cursor is in the plot window when it is drawn.

I'm not saying that a delay is the right fix, only that this behavior points to some kind of timing issue. If so, then maybe there is something we can do to avoid the problem?

I'm not sure about arch linux, but I've almost always compiled octave using qt4 in the past on ubuntu. And I do remember the configuration options showing qt5 as an option. I didn't even know that octave was built using qt5 in Arch Linux.

Octave is not able to show any plots when plotted in wayland session. I have tried this on Arch Linux in the gnome desktop environment running with wayland. The plot controls show up, but are unresponsive as the plot window is just filled with a black background. Resizing the plot window just leads to weird artefacts.

This behaviour does not happen when logged in with XOrg, although initially one has to resize the plot window in order to see the plot. Any subsequent plot works fine in Xorg except the initial plot.

However plotting using octave-cli works under both wayland and XOrg. The only issue is that it uses the old plotting interface instead of the modern one.

We automatically install a Jupyter kernelspec when installing thepython package. This location can be found using jupyter kernelspec list.If the default location is not desired, remove the directory for theoctave kernel, and install using python -m octave_kernel install. Seepython -m octave_kernel install --help for available options.

The command line options to Octave can also be specified with anOCTAVE_CLI_OPTIONS environment variable. The cli options be appended to thedefault opions of --interactive --quiet --no-init-file. Note that theinit file is explicitly called after the kernel has set more off to preventa lockup when the pager is invoked in ~/.octaverc.

An error that starts with gnuplot> set terminal aqua enhanced title can be fixed byadding setenv("GNUTERM","qt"); to ~/.octaverc on MacOS or by installinggunplot-x11 and using setenv("GNUTERM", "X11").

Set the environment variable OCTAVE_EXECUTABLE="octave"echo export OCTAVE_EXECUTABLE=\"octave\" >> ~/.bashrcMake a directory for the temporary plot directories that the kernel uses. This cannot be a hidden directory.mkdir ~/octavePlotsSet plot_dir to point to your plot directory in octave_kernel_config.py.c.OctaveKernel.plot_settings = dict(plot_dir='/octavePlots')where is the absolute path to your home directory. Do not use ~ as this resolves to a different location for Octave-Snap.

If you are using GNU/Octave on a Debian or Ubuntu based system, execute thiscommand in a terminal: sudo apt build-dep octave-psychtoolbox-3 and then goto step 2. If you are using Octave on a different Linux distribution (unsupportedby us, although it will probably work on many!) then you will need to track downand install various runtime dependencies manually.

Using a terminal on Fedora 26, you might type octave to start its use. In case you do not have it installed, a message to ask you to install is going to be displayed. Then you could type y or Y to allow Octave installation. e24fc04721
