    _______________________________________________________

Details:

The attached code fails when executed as a script (i.e., storing the file in
the current directory and typing "broadcasting" in the interactive octave
shell), reporting the following error:


error: +=: nonconformant arguments (op1 is 2x1x2, op2 is 2x1)
error: called from
    broadcasting at line 3 column 3


However, executing the command

A += B

interactively gives the expected result

A =

ans(:,:,1) =

   2
   2

ans(:,:,2) =

   2
   2


Other operators (e.g., ".*=") are affected by the same issue. I couldn't find
any information about broadcasting becoming deprecated anytime soon, but even
if it were, different behaviour in scripting and interactive mode is a bug in
my opinion.

Kind regards,
Markus
