GNU Octave is a high-level programming language, which is primarily for numerical computing. Octave helps linear and nonlinear problems numerically and to help other numerical experiments using language that is more relevant to MATLAB. It can also be used as a batch-oriented language. Being a part of the GNU project, it is free software according to the terms of the GNU General Public License. GNU Octave is written by C, C ++, Fortran and is available in 19 languages. Octave is one of the major free options in MATLAB, while there are some Scilab and FreeMat. Scilab, however, offers less emphasis on syntactic compatibility with MATLAB than the octave. In this article, we will learn How to install GNU Octave in Ubuntu – MATLAB (MathWorks) Alternative For Linux.
Follow the below steps to install GNU Octave in Ubuntu – MATLAB (MathWorks) Alternative For Linux:
Before starting the installation we have to install the official PPA repository for the GNU Octave application is not a part of the default repository of Ubuntu. So to install the PPA repository refers to the below command.
itsmarttricks@mangesh:~$ sudo add-apt-repository ppa:octave/stable [sudo] password for itsmarttricks: More info: https://launchpad.net/~octave/+archive/ubuntu/stable Press [ENTER] to continue or Ctrl-c to cancel adding it. Ign:1 cdrom://Ubuntu 18.04.1 LTS _Bionic Beaver_ - Release amd64 (20180725) bionic InRelease Err:2 cdrom://Ubuntu 18.04.1 LTS _Bionic Beaver_ - Release amd64 (20180725) bionic Release Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs Ign:3 http://ppa.launchpad.net/aseman/desktop-apps/ubuntu bionic InRelease Hit:4 http://in.archive.ubuntu.com/ubuntu bionic InRelease Hit:5 http://ppa.launchpad.net/audio-recorder/ppa/ubuntu bionic InRelease Reading package lists... Done
After installing the PPA repository let’s update the packages & repositories of Ubuntu using the below command to take effect.
itsmarttricks@mangesh:~$ sudo apt-get update Ign:1 cdrom://Ubuntu 18.04.1 LTS _Bionic Beaver_ - Release amd64 (20180725) bionic InRelease Err:2 cdrom://Ubuntu 18.04.1 LTS _Bionic Beaver_ - Release amd64 (20180725) bionic Release Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs Ign:3 http://dl.google.com/linux/chrome/deb stable InRelease Ign:4 http://ppa.launchpad.net/aseman/desktop-apps/ubuntu bionic InRelease Hit:5 http://download.virtualbox.org/virtualbox/debian bionic InRelease Hit:6 http://in.archive.ubuntu.com/ubuntu bionic InRelease Hit:7 http://security.ubuntu.com/ubuntu bionic-security InRelease Hit:8 http://ppa.launchpad.net/audio-recorder/ppa/ubuntu bionic InRelease Get:9 http://dl.google.com/linux/chrome/deb stable Release [943 B] Hit:10 http://in.archive.ubuntu.com/ubuntu bionic-updates InRelease
After the update the packages & repositories we are now ready to install the GNU Octave Application. So use the below command to install the same.
itsmarttricks@mangesh:~$ sudo apt-get install octave Reading package lists... Done Building dependency tree Reading state information...

As you can see above we have successfully installed the GNU Octave package. To confirm the same reference the below command.
itsmarttricks@mangesh:~$ sudo dpkg -l octave Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-====================================-=======================-=======================-============================================================================= ii octave 4.2.2-1ubuntu1 amd64 GNU Octave language for numerical computations
Now to open the application just type the command octave on the shell prompt. Refer to the command below.
