Is Matlab Free For Ubuntu

The problem is that (Matlab) is commercial and can be expensive. Recently I took a class on Machine Learning and was surprised to find that the professor was not going to use Matlab, but a Free Software alternative called GNU Octave, which was good news because it meant not having to spend money on a proprietary software. 10GB — download from Google Driver. 'Install Matlab R2018b on Ubuntu' is published by Le Hoang Long. Matlab 2017 free download. Most people looking for Matlab 2017 free downloaded: MATLAB Student. 3.6 on 193 votes. MATLAB is the language of technical computing at leading engineering and science companies and the standard software at more than 5000 universities worldwide.

Is Matlab free on Linux?Although pirated versions of MATLAB for Linux are available all over the Internet, I personally don't recommend that you install them as I do not support piracy. There's in fact a totally legal and free way to run your MATLAB programs on Linux. It's called GNU Octave. Octave is totally free and open-source.
Is octave the same as Matlab?GNU Octave is mostly compatible with MATLAB. However, Octave's parser allows some (often very useful) syntax that MATLAB's does not, so programs written for Octave might not run in MATLAB. This page also contains notes on differences between things that are different between Octave (in traditional mode) and MATLAB.

Is Matlab better than R?Matlab and R are both very useful but R is free and has a hugh library of very useful packages. Why not learn some R and use both? You'll know when a language is better than other for some application. I would go also with python + pandas, that is a quite open source pack to learn too.
Is Matlab faster than Python?While it depends on implementations and other factors, my perception is Python is faster overall. MATLAB is a memory pig. Numerical data is treated as complex doubles. So, at the limits of processing, Python will be faster.
Why is Matlab used?Why should we use MATLAB (Matrix Laboratory) MATLAB has several advantages over other methods or languages: Its basic data element is the matrix. Several mathematical operations that work on arrays or matrices are built-in to the Matlab environment.

Two different approaches are going to be adopted:
 1. If you are the only user who will use matlab then follow the first step (#1).
 2. If there are several users who will use matlab with several user accounts then follow second step (#2).
#1. installing in home directory:
Ubuntu 16.04 Matlabinstalling matlab in /usr/local (explained in the second section of this tutorial) is troublesome and requires root permission in several steps. installing it in the home directory is the easiest way.
 just follow the steps below:
 1. mount the iso (better use furiusisomount)
 2. go to the newly mounted volume
3. right click mouse and select 'open in terminal' & enter the command ./install
 or
3. double click on the 'install' file and select 'run in terminal' .
 4. Now a matlab installation window will appear. go through the general processes like 'next' , 'accept', check 'install without internet', put your license key where it is needed.
5. When matlab installation folder selection window appears erase all the text in the text box and put /home/Your_user_name/Matlab and continue . (the default path is /usr/local/Matlab/Rxxx, don't use it)
 6. Now everything will go smooth, brows your lic_standalone.dat file when needed.
 7. after completing the installation enter the following code into terminal:
sudo ln -s /lib/i386-linux-gnu/libc.so.6 /lib/libc.so.6
this is for a warning that libc.so.6 can not be found.
Now matlab is installed in /home/user/Matlab directory. 
run Matlab:
go to the home/user/Matlab/bin directory and double click on matlab and 'select run in terminal' or enter command in terminal:
/home/user/Matlab/bin/matlab
here user = your user name
or, to run from the menu, follow these steps:
 1. in the terminal enter this code:
 sudo gedit /usr/share/applications/matlab.desktop
 2. copy paste the following lines into the newly opened .desktop file
[Desktop Entry]
 Exec=/home/user/Matlab/bin/matlab -desktop
 Icon=/home/user/Matlab/X11/icons/matlab64c_icon.xpm
 Type=Application
 Comment=Matrix Laboratory
 Name=Matlab
 Categories=Development;
user will be replaced by your user name. (must).
For Exec and Icon, the path should be correct i.e you must change 'user' according to your path. (must).
in 'Name= Matlab ' you can change the name whatever you want.(optional).
in 'GenericName' you can put whatever you want. you can cut off this line too.(optional).
save & exit the .desktop file.

 a new entry named 'Matlab' will be added in the menu under the programming section.
 3. now go to menu->programming->Matlab.
Matlab Ubuntu Download Enjoy.. your Matlab environment..
#2. installing in /usr/local directory:
 if there are several users in a single pc & each of them has individual user accounts and need to use the same application then it is required to install it in the directory indicated by default in matlab installation process i.e in /usr/loal
 steps:
 1. mount the iso (with furiusisomount). if you already have the contents of the iso copied elsewhere then skip this step.
 2. create a directory /home/user/matlab.(it's temporarilly, after installation this can be deleted.)

 run in terminal (to create the directory):
mkdir /home/user/matlab
user=your user name.
 copy the contents of the iso (archives, bin, etc, java, sys, install,.....) in your /home/user/matlab folder.
If you want to avoid copying, then mount the iso with this command:
sudo mount -o loop path_to_the_iso_file_matlabxxx.iso /mnt
then
