Re: feval in .oct files?

Hi,

I am using the following include files:

#include <octave/config.h>
#include <iostream.h>
#include <octave/oct.h>
#include <octave/defun-dld.h>
#include <octave/error.h>
#include <octave/oct-obj.h>
#include <octave/pager.h>
#include <octave/symtab.h>
#include <octave/variables.h>
#include <octave/toplev.h>
#include <octave/Array3.h>
#include <octave/parse.h>

As far as I remember when I ported my stuff to 2.1X, the declaration
of feval is in parse.h (but I am not sure right now).

With casting it should work 
        int NumTrials = (int)(args(0).double_value())
or
        Matrix M = new Matrix((int)NumTrials,...)
