Re: how to instal, or upgrade, the latest octave version on windows 7

[Mircea Toma]

Thanks.

I tried the same HelloWorld.cc and it worked well for me too. The one that gave me the error is:

     #include <octave/oct.h>
     
     DEFUN_DLD (helloworld, args, nargout,
       "Hello World Help String")
     {
       int nargin = args.length ();
       octave_stdout << "Hello World has " << nargin
             << " input arguments and "
             << nargout << " output arguments.\n";
       return octave_value_list ();
     }

from: 
http://www.gnu.org/software/octave/doc/interpreter/Getting-Started-with-Oct_002dFiles.html

I am not sure what DEFUN_OLD is suppose to be. And I am not sure if this is suppose to work as it. 
thanks again.
Mircea

Hello

I have used the following source in the octave manual.

//HelloWorld.cc
#include <iostream>
#include <octave/oct.h>
   
    int
    main (void)
    {
      std::cout << "Hello Octave world!\n";
      int n = 2;
      Matrix a_matrix = Matrix (n, n);
      for (octave_idx_type i = 0; i < n; i++)
        {
          for (octave_idx_type j = 0; j < n; j++)
            {
              a_matrix (i, j) = (i + 1) * 10 + (j + 1);
            }
        }
      std::cout << a_matrix;
      return 0;
    }
// End of HelloWorld.cc


octave:5> mkoctfile --link-stand-alone HelloWorld.cc -o HelloWorld
octave:6> system ('HelloWorld')
Hello Octave world!
11 12
21 22
ans = 0

Worked as expected

Regards

Tatsuro
