problem plotting "N-d object"

[Sergei Steshenko]

Hello,

here is a screen session:

"
octave:3> foo(1,1,:) = [1 2 3]
foo =

ans(:,:,1) =  1
ans(:,:,2) =  2
ans(:,:,3) =  3

octave:4> plot(foo(1,1,:));
error: transpose not defined for N-d objects
error: called from:
error:

octave:4> plot(foo(1,1,:)(:));
octave:5>             

".

I don't understand why 'octave' complains about N-d objects - to me 
"foo(1,1,:)" looks like a 1-d object. Because the first two of the three 
indexes are fixed in the expression.


And adding "(:)" solves the problem.

Just wondering - should it be that hard for end user ? Does Matlab behave the 
sane way ?

Thanks,
  Sergei.
