It is the equivalent of swig for Octave and Matlab and can be found at 
   http://lnc.usc.edu/~holt/matwrap/

If you use Debian, you can simply use the matwrap package I maintain. FYI its
Description fields reads as follows:

Description: A wrapper generator for matrix languages
 Matwrap is a tool for interfacing C++ code into matrix-oriented scripting
 languages such as Octave, Tela or Matlab 5
 .
 It generates all the code to convert from the scripting language's internal
 types into the types that your C++ code understands (e.g., double, char *,
 float *, struct abc *). You do not need to understand any of the API details
 of the language to use your C++ code; just give matwrap a .h file describing
 your functions.
 .
 Brief list of features:
 .
  - Functions are automatically vectorized.
  - Arguments containing dimensions of other vector and matrix arguments can
    be computed automatically and need  not be specified.
  - Pointers to structures and classes are supported. Public member functions
    of classes may be called, and public data members may be evaluated or
    set. Inheritance is supported.
