How to embed the GNU Octave in C/C++ program?

Question

I want to calculate some matrix algorithms using the GNU Octave library. I know I can use C/C++ API of Octave for basic use. However the method I want to use is not in the default packages of Octave. So how to use Octave's control package in the C/C++ program?

Answer 1

Something like this

embed.cpp

#include <iostream>
#include <octave/octave.h>

int main(int argc,char* argv)
{
  int embedded;
  octave_main(argc,argv,embedded=0);  
  return embedded;
}

Then

mkoctfile embed.cpp --link-stand-alone -o embed in order to make a standalone executable.

To call octave functions whether they are provided by scripts or octaveforge modules you can then use feval which takes the octave function name as string, an octave_value_list of the input variables to that function, and the number of variables to that function as integer.
