==Octave server VM installer for OSX 10.10 Yosemite and OS X 10.11 El Capitan==

[http://deepneural.blogspot.fr/p/welcome.html Configuration files] that cause Vagrant to automatically download and configure an Octave server VM under OS X including 10.10 Yosemite. The install process pulls down the latest stable Linux version of Octave at the time of installation. All software used in running this server VM is open source (Vagrant, VirtualBox, Octave). The Octave server will run headless, and display the Octave GUI and graphics on the host via the Mac's native X-windows server. The recommended configuration ensures that by default user files written by the GUI are in a folder shared with the Mac's filesystem, and the VM suspends automatically when the user quits the GUI. Any edited files then persist in the Mac's shared folder.

*If you had installed Mac Ports in the past already, update it first by typing {{Codeline|sudo port selfupdate}} and {{Codeline|sudo port upgrade outdated}} in the terminal.

*MacPorts has good support for Octave. A list of what MacPorts has available for Octave is [http://www.macports.org/ports.php?by=name&substr=octave here]. To install the most recent version of Octave, type {{Codeline|sudo port install octave}} or if you want the experimental graphic user interface (GUI) {{Codeline|sudo port install octave +gui}} at the Terminal's command line. Octave has many dependencies which will be downloaded and installed prior to Octave. The entire installation process can take a few hours.

*The variant installed may be important to the user's experience.  The available variants for  {{Codeline|octave}} are displayed by typing {{Codeline|port variants octave}}.  In MacPorts 2.3.3 the variants ''atlas'', ''gcc49'' and ''glgui'' are installed by default (marked with '+' sign in {{Codeline|port variants octave}} output). For the experimental GUI add variant +gui (see above). If you need Java support add the new Java variant (+java).

*Octave depends on arpack. Unfortunately arpack is installed with the ''accelerate'' variant by default. The ''accelerate'' variant uses Apple's Vector Libraries which have some known bugs that can cause Octave to crash if using certain functions in arpack. To avoid this install arpack with the ''atlas'' instead of the ''accelerate'' variant {{Codeline|sudo port install arpack -accelerate+atlas}}. You can even do this after you installed Octave. The new variant become active by default.

*If Octave crashes when plotting use the Gnuplot graphic toolkit instead of FLTK. Type {{Codeline|graphics_toolkit('gnuplot')}} in Octave before plotting. For using the nicer wxt-terminal of Gnuplot, type {{Codeline|setenv("GNUTERM","wxt")}} in Octave. To make this the standard behavior append both commands in one of Octave's startup files e.g. your {{Codeline|~/.octaverc}}.

This would install octave with the default dependencies. Note that the default dependencies include java runtime environment. If you do not have java installed, homebrew would guide you to do that. Or you can type {{Codeline|brew install octave --without-java}} to remove its dependency on java.
