NDarray, inner/outer tensor products

[daniel heiserer]

Hi,

is there a way to create the inner and outer product of a NDarray?

eg:
b=rand(3,4,5);
c=rand(3,2);

d=tensor_product(b,c,[1 1]);
==> size(d)= 4 5 2

or with multiple "condensations":
b=rand(3,4,5);
c=rand(3,4);

d=tensor_product(b,c,[1 1;2 2]);
==> size(d)= 1

the outer product would be without/empty  third argument:
b=rand(3,4,5);
c=rand(3,4);

d=tensor_product(b,c);
==> size(d)= 3 4 5 3 4
