On an ending note, Octave has proven throughout its years of existence that it’s a reliable programming language, capable of sustaining developers in their endeavor to create math and physics applications without paying a dime. Regardless of your choice, Octave sports flexibility, allowing you to use the collection of libraries bundled inside it to develop math related projects, as well as to extend it through user-defined functions that can be written inside Octave itself or by loading modules developed in other programming languages.Īside from delivering a library set that allows for the programming of numerical systems, Octave also bundles support for extensive graphics, which include data manipulation and visualization. The program is presented inside a large-sized package, no matter if you opt for the VS or MinGW approach, with the former being packed inside an installer and the latter, slightly larger, inside an archive. Octave provides a command line approach for the applications being built inside it, although the development of non-interactive problems is supported as well. Numerical experiments, support for linear and nonlinear equations, polynomial manipulation, as well as other common algebra problems are all within Octave’s range of possibilities. Suitable environment for math enthusiastsĪvailable as individual packages for both Visual Studio and MinGW, Octave’s primary purpose is bent on providing a high-level language that sports high compatibility with Matlab.

Octave is a programming language oriented towards numerical computations, with emphasis on developing software for bioinformatics, mechanics and instrument control. There are various applications that let you express your ideas and virtually bring them to life. configure -prefix=/home/dextop/packages/SOURCE/octave-5.1.0/ehm_build -with-lapack=/usr/lib/liblapack.so -with-blas=/usr/lib/libblas.One of the most useful functions of a computer, that which represents the backbone of every modern device is programming.
Anything else I should try or log files I should send? Perhaps someone else might have some ideas. I tried looking at the output of strace, but I didn't see anything that stuck out. This produces the same kind of hang.īoth hangs go to "defunct" when looking at "ps aux | grep octave". I don't even know if this is where I should be looking for that issue.
I tried both qt, and gnuplot for plotting, but it fails to produce a plot when compiling with or without opengl. So I recompiled with different BLAS and LAPACK libraries available (openblas, blas, etc.) but no matter which blas and lapack libraries I link to it still hangs.Ģ. However if I try to invert the matrix, octave hangs. I can input a matrix and take its transpose. I can do simple things like add 1+1, so octave is up and running. the gui starts up just fine, and octave also starts just fine.

I have successfully compiled Octave 5.1.0 on "Linux on Dex" (LoD), the linux environment available on android on some samsung phones and tablets. Mon 12:14:15 AM UTC, original submission: Quote I think your intuition different BLAS and LAPACK is a good start, but it's not clear that you aren't building with OpenBLAS every time. You can also try completely removing all traces of OpenBLAS libraries using apt or dnf or whatever your package manager is. You can try running "version -blas" in Octave to see what it detects. If this system is an apt-based distribution, it's possible that you are linking against OpenBLAS even when you think you are linking against the reference BLAS library due to the alternatives system.
Can you confirm with gdb or possibly ltrace that the hang is in one of the numerical libraries in both cases? The plot routines are probably also performing matrix operations, so possibly also hanging on a BLAS or LAPACK routine. If both issues hang in the same way, then I would say it's possible that it's the same underlying issue. Thank you for your bug report and for trying to provide as many details as you can. There is also a shared memory directory mounted: Tasks: 39 total, 1 running, 35 sleeping, 0 stopped, 3 zombie So, using "gnuplot" as the graphics_toolkit it, and calling "plot" it opens up a plot window but doesn't draw anything in it. The plotting routine still hangs, but this time it gives me an error. GNU Octave is an interpretive command language for scientific and mathematical computational operations. After removing openblas from the system it returned ATLAS (which I also have installed). Thank you for the quick reply! You are correct, it was openblas.
