Answer 1

Since I have already found a solution to this problem wasting a day, I just want to share it:

This seems to be a problem of MATLAB MCR installation script designed for Linux by MathWorks. Furthermore, it is a result of a known Ubuntu bug. To fix it, add your MCR to the $PATH as shown below:

• First make sure to add the missing files to the right folder, in terminal:

  sudo cp /usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/runtime/glnxa64/* /usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/bin/glnxa64
  

• Add the proper library folder to your .profile, such that this change will stay after logout

  ubuntu: gedit .profile
  

  In the end of the file add following lines:

  #MATLAB MCR
  
  export LD_LIBRARY_PATH=/usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/bin/glnxa64
  export XAPPLRESDIR=/usr/local/MATLAB/MATLAB_Compiler_Runtime/v83/X11/app-defaults
  
  export PATH=$PATH:$LD_LIBRARY_PATH
  export PATH=$PATH:$XAPPLRESDIR
  

• Invoke following code in the terminal to make sure that Ubuntu bug doesn't re-write your variable:

  echo STARTUP=\"/usr/bin/env LD_LIBRARY_PATH=\${LD_LIBRARY_PATH} \${STARTUP}\" | sudo tee /etc/X11/Xsession.d/90preserve_ld_library_path
  

• Reboot

If this solution doesn't work, try to reinstall MATLAB MCR 8.3 from the MathWorks website and repeat the steps.
