In this article, I will show you how to install and get started with GNU Octave on macOS. In order to test the installation and to exemplify the usage, I will show you how to use Octave for a simple image processing application.

At the time of this writing, the latest stable version of Octave is 5.1.0. Unfortunately the graphical interface of Octave 5.1.0 is buggy on macOS and tends to freeze randomly. If you are OK with using the CLI interface of Octave, you can use version 5.1.0. See the second part of this article for a quick how to install and setup.

Since most Octave users will prefer the GUI interface, I will first show you how to install Octave 4.4.1, which seems to be more stable than 5.1.0 on macOS when used in GUI mode.

I assume that you have the Command Line Tools installed on your machine. If this is not the case, write the next command in a Terminal and accept the defaults:

The article consists of three parts:

At this time, there is no official installer for Octave for macOS. In order to install 4.4.1 we are going to use the Octave.app build. Go to the Download page and get the Current Release of Octave. You should end up with a file named Octave-4.4.1.dmg in your Downloads folder.

Version 4.4.1 depends on OpenJDK 11.0.2+9 which you can get from the OpenJDKarchive. Make sure that you pick the exact version mentioned before. In order to install OpenJDK 11.0.2, open a Terminal and execute the next commands:

Once you’ve installed the required version of Java, you can proceed with installing Octave. Double click on the dmg file, accept the license and drag the app to your Applications folder. Since this is a third party unsigned build, first time when you start Octave you will need to right click the app and select Open.

You’ll also need to instruct Octave to use the GnuPlot graphics backend for plotting graphics. The default qt backend seems to be pretty buggy on macOS. In order to do this, you’ll need to create a .octaverc file in your home folder and put the next two lines in this file:

A simple way to do the above is to run the next commands in a Terminal

Restart Octave in order for the above to take effect.

At this point, you should be able to use Octave normally and use the menus to select the working folder, open, save files and so on. Go to the last part of this article if you want to see an example of using the app.

At this time, there is no official installer for Octave for macOS. In order to install 5.1.0 we are going to use the Homebrew package manager. If you don’t have Homebrew installed, you can install it by running the next command in a Terminal:

Start by making sure that your Homebrew installation is up to date:

Finally, install Octave on your system:

The above command will take some time, because Octave depends on a lot of other libraries. Once the installation is finished, you can invoke the Octave interpreter with the octave command in a Terminal:

If you really want to start the GUI interface, keep in mind that, at least for version 5.1.0, this is pretty unstable, use:

You’ll also need to instruct Octave to use the GnuPlot graphical backend for plotting graphics. The default qt backend seems to be pretty buggy on macOS. In order to do this, you’ll need to create a .octaverc file in your home folder and put the next two lines in this file:

A simple way to do the above is to run the next commands in a Terminal

Restart Octave in order for the above to take effect.

At this point, you should be able to use the Octave CLI interface normally.

If you want to evaluate an existing Octave script, you can do it in a few ways. I’ll assume that you have a file named demo1.m in your current folder.

First start the interpreter and than run the script from an interpreter prompt:

The second option is to run the script when you start the interpreter and after the script is finished you will be back at the interpreter prompt:

If you just want to run a script and exit when done, simply use:

In the final part of this article I will show you how to install the Octave image processing package. This should work the same for Octave 4.4.1 or 5.1.0. Start Octave and write the next command at an Octave prompt:

The above will install the image package for Octave. You need to run this command only once after which it will remain installed on your system.

By default, Octave doesn’t load a newly installed package when you start it. In order to use an existing package, use the next command at an Octave prompt:

If you want Octave to always load an already installed package, add the load command to your .octaverc file, e.g. by running in a Terminal:

Next time when you will start Octave it will also load the image package.

Download clouds.jpg to your working folder and run the next script (I assume that you’ve already installed and loaded the image package):

This is what I see if I run the above script on my Mac in the Octave 4.4.1 app:

What is GNU Octave ?

If you are an Engineering student or graduate engineer, then you are definitely familiar with Matlab or Octave. You may not be familiar with Octave but probably you know about MATLAB. In case if you do not know, GNU Octave is software featuring a high level language which widely used for numerical computations. Octave is free alternative of MATLAB. In case you do not know that MATLAB is very expensive software which is nearly impossible for students to buy it. GNU Octave is fully free and you can use the same programming syntax that you have been using on MATLAB. If you are a computer programmer who likes numerical computations, Octave is appropriate for you. Let’s install Octave together.

How to install GNU Octave ?

Usually you may find many articles about installing Octave on Mac OS which is only installation inside Terminal. As a result you do not get GUI program where you can work like MATLAB. We are going to install the GUI program that will provide MATLAB like GUI program.

Step 1: Download GNU Octave (GUI) installer for Mac OS.

First of all we need to download the installer file by clicking on the download button below. If you click the download button then it will take you to a Sourceforge webpage where the installer file located.

Wait for few seconds and the installer file (GNU_Octave_3.8.0-6.dmg) will begin to download as shown in the photo.

Step 2: Install GNU Octave.

Once the installer file is downloaded, go to the Downloads folder (where the downloaded file located).

Double click on the downloaded installer file. You will see the window as shown in the photo below.

Double click on the icon Octave-3.8.0-6.mpkg (as marked on the photo). You may see the pop up message as shown below.

By default your Mac OS only allows to install Mac which is from Mac App Store or verified developers. So we need to give the permission to install manually.

Open system preference from Dock or Spotlight.

Click on the icon “Security & Privacy ” from System Preference. App installation permission is under this setting. In the photo below you can see the icon marked in the red circle.

A message notification may appear on the screen where you need to click “open” button.

Now you will be able to see the GNU Octave installer window. This installation process very easy like windows software installation where you just need to click “Continue”. Also in the next window click “Continue”.

This step is very important where we will customise our setting. Click “Customize” button as marked left.

Sep 26, 2019  The best thing you can do to protect your Mac is to keep it updated and install only signed software from approved developers and the Mac App Store. And—in case you’re wondering—the author of this piece doesn’t have an antivirus on his Mac. Do Macs get viruses? Do Macs need antivirus software? The answer isn't as simple as it may seem. In this article, we look at the dangers faced by Mac users and the pros and cons of using Mac. Do i need antivirus for mac os high sierra.

If you click on “Customize” button then you will see several options as shown in the photo below. Make sure “Octave-3.8.0-cli” is unchecked. Then click “Install” button.

It may take a while to install on your computer. If successfully installed then you will see the window as shown below.

Step 3: Update GNU Octave.

You may noticed that we have installed an older version of Octave on our computer but this is not what we want. We want to install the latest version of Octave. To update Octave we need a third party program to be installed in our Terminal which is called “Homebrew”. Homebrew is very popular to program to programmers because it helps to install open source programs on Mac OS.

First of all, we need to open Terminal. You can open terminal form Launchpad or Spotlight search. Press command + space and type Terminal as shown in the photo. Then simply press return.

Copy the line of terminal command and paste into terminal then press return.

/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

Wait for few minutes until the installation is done. If homebrew is successfully installed then copy the line of command below and paste it in terminal.

brew install octave
