[Matlab] When installing matlab and matlab.engine

[bwijerat]

I feel it would be valuable to provide some advice for installation and use for those unfamiliar with the matlab in linux, and the matlab.engine which is used to call matlab from python.

Using MATLAB in Ubuntu (after installation and activation):

• create a symbolic link to open MATLAB via command 'matlab' from any terminal
• my installation directory for MATLAB R2018b was: '/usr/local/MATLAB/R2018b'
• add MATLAB bin folder containing executable script to PATH, choose one of the following: 1) export PATH="/usr/local/MATLAB/R2018b/bin:$PATH" restart terminal OR source ~/.bashrc 2) sudo gedit ~/.bashrc (append) export PATH="/usr/local/MATLAB/R2018b/bin:$PATH" restart terminal OR source ~/.bashrc
• open MATLAB via terminal command 'matlab'

Installing MATLAB Engine API for Python https://www.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html

This may fail (permission problems, but then using sudo fails to properly install it too):

cd "matlabroot/extern/engines/python"
python setup.py install

This worked for me (Ubuntu 16.04 LTS, Python 2.7, 3.5, 3.6, Anaconda 4.3): https://stackoverflow.com/questions/45016671/import-error-no-module-named-matlab-engine

cd "matlabroot\extern\engines\python"
python setup.py build --build-base=$(mktemp -d) install

Test matlab.engine via commands (output: True): https://www.youtube.com/watch?v=yhnB7zWgi_Q

import matlab.engine
eng = matlab.engine.start_matlab()
tf = eng.isprime(37)
print(tf)

Thanks for the info! Mind if I modify this a bit and add it to the repo wiki?

Of course, please go ahead and thanks for the quick response
