The repository homebrew/science is dead, long live dpo/homebrew-openblas! We switched from Apples proprietary Accelerate framework to OpenBLAS, so free your numbers and compile Octave as follows
brew tap dpo/openblas
Pin the repository
brew tap-pin dpo/openblas
Now, install a development snapshot of octave (with GUI and java)
brew install dpo/openblas/octave --devel --with-qt --with-java
MacOS and Linux users with HiDPI screen will enjoy improved plotting thanks to the fixes of jpswensen
for bug #49053
The best option to install Octave on macOS with a stable graphical user interface is via homebrew (sorry macports). Get the latest formula from dpo‘s repository. Please see the most recent post on how to install it.
Since a few days the most obvious Octave bug on Mac OS X has been fixed: the alignment of dock widget titles, see commit e870a68742a6 (thanks Marius and Torsten). Homebrew users can try it immediately by compiling the development sources, i.e.,
brew uninstall octave
brew install octave --with-gui --HEAD
Rik gave a nice summary at OctConf 2015 on how to write high performance m-files. An updated version of the slides and many more can be found in the Octave Wiki: http://wiki.octave.org/OctConf_2015#Slides
ONELAB is an interface to finite element software, i.e., Gmsh and GetDP, for engineering applications. Homebrew science has been updated such that you can easily compile your own build on the Mac (after having installed brew):
> brew tap homebrew/science
> brew install gmsh --HEAD --with-fltk --with-petsc --with-slepc --with-opencascade
> brew install getdp --HEAD --with-petsc --with-slepc
A new major version of Octave (3.8.0) has been released. The sources are as usual at www.octave.org
but a nice installer for the Mac binary
can be found on sourceforge
. The macports version is not ready
Textmate is a great OpenSource text editor for Mac OS. It can handle many programming languages (syntax highlighting, snippets, special commands) by bundles.
You find at GitHub my fork of the Matlab Textmate Bundle. It features improved Octave syntax support and allows to execute code by pressing [CMD]+R. The script looks for a terminal running Octave (or Matlab) and pastes the code by Applescript (similar to the code of DGrady).
Next week I will attend OctConf 2013. From the official announcement: “Following the success of OctConf 2012 which brought together users and developers for five days in July in the French Canadian summer, the first european OctConf will be held in Milan, Italy on June 24-26 2013”. I will give an invited talk on “Niobe – an Octave/Matlab Based Environment for Coupled Low-Frequency Electromagnetic Field Simulations in Teaching and Research”, co-author is Herbert De Gersem (with contributions from A. Bartel, M. Clemens, M. Günther, C. Kaufmann, J. ter Maten and D. Schmidthäusler). You can find the slides here.
UPDATE 1: Live Blog at Octave’s Google+ site.
UPDATE 2: At OctConf 2013 were several presentation given from Google Summer of Code students, for example one deals with new incomplete factorizations for preconditioning (by Kai Torben Ohlhus) and another one is concerned with a general purpose PDE package (Gedeone). Stay tuned!
Today a brand new nVidia K20 with Kepler architecture arrived in my office in Darmstadt. It was immediately configured thanks to our administrator Christian Schmitt. The card will be used to accelerate the solution process of linear systems in finite difference based schemes. This is a joint research work with Christian Richter and Markus Clemens. We aim to present first results at the nineteenth COMPUMAG Conference on the Computation of Electromagnetic Fields which is held from June, 30 to July, 4 in Budapest, Hungary.
We have relaunched the website of the research project SOFA for “Gekoppelte Simulation und Optimierung für robustes virtuelles Fahrzeugdesign” granted by the German Federal Ministry of Education and Research (grant numbers 03MS648X). The new website is here: http://www.sofa-verbund.de.
