+Troubleshooting
+---------------
+
+On Ubuntu, you may encounter an error similar to the following::
+
+    /usr/local/MATLAB/R2017a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found.
+
+If so, modify your MATLAB installation as follows:
+
+.. code-block:: shell
+
+    cd /usr/local/MATLAB/R2017a/sys/os/glnxa64
+    sudo rm libgfortran.so.3 libquadmath.so.0 libstdc++.so.6
+    sudo ln -s /usr/lib/x86_64-linux-gnu/libgfortran.so.3 libgfortran.so.3
+    sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 libstdc++.so.6
+    sudo ln -s /usr/lib/x86_64-linux-gnu/libquadmath.so.0 libquadmath.so.0
