+            dlib contains a tool that makes it easy to call C++ code from MATLAB.  It's
+            documented in the examples in the dlib/matlab folder.  In particular, the
+            <a href="dlib/matlab/example_mex_function.cpp.html">dlib/matlab/example_mex_function.cpp</a> and
+            <a href="dlib/matlab/example_mex_callback.cpp.html">dlib/matlab/example_mex_callback.cpp</a> examples.
+            You can also easily compile these files using CMake.  See the instructions in the README file
+            in the dlib/matlab folder for further details.
