Another example of this in Octave sources could be the implementation of ode15i 
as a wrapper to the sundials IDA library:

  
http://hg.savannah.gnu.org/hgweb/octave/file/c3cfd3115b78/libinterp/dldfcn/__ode15__.cc

The most simple example of storing and calling an Octave function from a C++ 
program 
is in the examples ditributed with Octave sources:
