How to write the code for the following multidimensional thing:
for s=1:n;
A(:,:,s)=[1 2 3]; B(:,:,s)=[10 20 30]
then result should come as
C(:,:,s)=[11 12 13;21 22 23;31 32 33]
the Third dimension is very important

Please take a look of functions BSXFUN and PERMUTE

see the documentation for bsxfun. It only works with scalars, vectors,
and 2D data, but when you loop around like that, you are really only
working with vectors.

Are you saying that bsxfun only works with 1- or 2-D inputs? That's not
right -- it works with inputs of any dimension.

I don't know what the OP is asking or I'd offer up a solution.

Hmmm, multiple dimensions does seem to be what is documented, but a few
days ago I received an error message from bsxfun in 2008b specifically
saying that the arrays had to be at most 2D. Perhaps that only applied
to some specific usages.
