I\'m trying to Use Octave with Visual C++.

I have downloaded octave-3.6.1-vs2010-setup-1.exe. Created a new project, added octave include folder to incl

Answer 1

I tried it myself, and the problem seems to originate from the feval line.

Now I don't have an explanation as to why, but the problem was solved by simply switching to the "Release" configuration instead of the "Debug" configuration.

I am using the Octave3.6.1_vs2010 build, with VS2010 on WinXP.

Here is the code I tested:

#include 
#include 
#include 
#include 

int main(int argc, char **argv)
{
    // Init Octave interpreter
    if (!octave_main(argc, argv, true)) {
        error("Octave interpreter initialization failed");
    }

    // x = rand(10,1)
    ColumnVector sz(2);
    sz(0) = 10; sz(1) = 1;
    octave_value_list in = octave_value(sz);
    octave_value_list out = feval("rand", in, 1);

    // print random numbers
    if (!error_state && out.length () > 0) {
        Matrix x( out(0).matrix_value() );
        std::cout << "x = \n" << x << std::endl;
    }

    return 0;
}

with an output:

x =
 0.165897
 0.0239711
 0.957456
 0.830028
