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?

  • I am new to use Octave in C++. Can you please show me how to use C/C++ API of Octave to realize it. Thank you very much! – Timothy May 15 '14 at 02:18

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.

See here for further information.

    Food for thought for anyone who lands here: using embed octave means you must release your code under a GPL like license http://wiki.octave.org/FAQ#If_I_write_code_using_Octave_do_I_have_to_release_it_under_the_GPL.3F – waiting4op2deliver Nov 19 '16 at 06:36
