title: libXp.so library missing on Ubuntu 16.04
body: <p>I'm trying to install Matlab on my Ubuntu 16.04 (64 bit), and it says <strong>'the X11 library libXp.so does not exist. Matlab won't run on this machine until the library is installed'</strong>. I followed some other forums about this problem, and the instruction was to install libxp6 (<code>sudo apt-get install libxp6</code>). I did so, but the problem still persists. I searched for the libxp.so library on my system but couldn't find it.</p>
  
  <p>When tryng to run Matlab from the bin folder using <code>./matlab</code>, it says <strong>error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory</strong></p>
  
  <p>How do I install the libxp.so on ubuntu 16.04? Do I need to run any specific package for it? If libXp.so is installed, then how do I locate the .so library? Please help.</p>
