Dirk,

Am not sure I understand the problem.  Isn't this doing
what you ask?

octave:2> x=1:10;
octave:3> x(:)
ans =
 
   1   2   3   4   5   6   7   8   9  10
 
octave:4> y=zeros(10,1);
octave:5> y(:)=x
y =
 
   1
   2
   3
   4
   5
   6
   7
   8
   9
  10
 

Notice that I deliberately tried to confuse octave
by feeding y (10 rows, 1 column) the vector x
(10 columns, 1 row).
