Joel,
Yes you can do this.  You can see some examples of how this is done from the 
Octave sources.  In case you just want to browse through them, you can see the 
files at the following link
http://hg.savannah.gnu.org/hgweb/octave/file/ee4775d04d7f/examples
Of particular interest, based on your problem description, is the file 
embedded.cc and standalone.cc.  Many of the other files are examples of calling 
C++ code from Octave.

Another route is to use the Octave engine package.  I am pretty sure the syntax 
of the Octave engine package is similar/identical to the Matlab engine 
interface (http://octave.sourceforge.net/engine/index.html).  I'm not sure the 
exact method you currently use to call Matlab from C++, but you have several 
options to do a similar thing from Octave.
