oct and arrays

[Jesper Schmidt Hansen]

Hi all,

I have been wondering about this for some time now.

DEFUN_DLD(octsum, argv, , "Some help text"){
  octave_value_list retval;

  // Checking inputs etc

Matrix A( argv(0).matrix_value() );     
  size_t nr = A.rows();
  size_t nc = A.cols();

  // Sum the elements
  double sum = 0.0;
  for ( size_t i=0; i<nr; i++ )
    for ( size_t j=0; j<nc; j++ )
      sum += A(i,j);

  retval = sum;

  return retval;
}
