Re: standalone application (octave to c++): define anonymous function for nonlin_curvefit()

[mmuetzel]

I didn't try this myself. But that part of your code:
    std::string f = "@(p,x) 1-exp(p(1)*x)";
    extern octave_value make_fcn_handle(const std::string& f, bool
local_funcs = true);
    octave_value_list result = octave::feval("nonlin_curvefit", ovl(f, init,
x_val, y_val, opt(0)), 4);

should probably better be:
    std::string f = "@(p,x) 1-exp(p(1)*x)";
    octave_value_list result = octave::feval("nonlin_curvefit",
ovl(make_fcn_handle(f), init, x_val, y_val, opt(0)), 4);
