Details:

Yet another quirk related to traling singleton dimensions. The subsasgn method
does not handle them consistently:


octave-3.2.4:1> x=ones(2)
x =

   1   1
   1   1

octave-3.2.4:2> size(x)
ans =

   2   2

octave-3.2.4:3> y=x(:,:,1)
y =

   1   1
   1   1

octave-3.2.4:4> size(z)
ans =

   2   2



That's ok. But then:


octave-3.2.4:5> z=x(:,:,:)
z =

   1   1
   1   1



octave-3.2.4:6> size(z)
ans =

   2   2   1



This last operation should return the same as the previous one, I think.
