indexing in octfile

Hello,

I have a question about doing indexing in an oct file.

If the following cc code:

  Matrix m = args(0).matrix_value();
  idx_vector idx(Range (3,6));
  Matrix ret = (Matrix) m.index (idx, 0);

is equivalent to the following octave code:

  ret=m(3:6);

what is the equivalent cc code for:

m(3:6)=5

or

m(3:6)=6:8;

or

m(3:6)=m(3:6)+6:8;

?


thanks!
