• Outer[f, , , ... ] gives the generalized outer product of the , forming all possible combinations of the lowest-level elements in each of them, and feeding them as arguments to f.
• Outer[f, , , ... , n] treats as separate elements only sublists at level n in the .
• Outer[f, , , ... , , , ... ] treats as separate elements only sublists at level in the corresponding .
• Outer[Times, , ]
gives an outer product.
• The result of applying Outer
to the tensors
is the tensor
with elements f[,]
. Applying Outer
to two tensors of ranks
gives a tensor of rank
• The heads of all
must be the same, but need not necessarily be List
need not necessarily be cuboidal arrays.
• The specifications
of levels must be positive integers, Infinity
• If only a single level specification is given, it is assumed to apply to all the
. If there are several
, but fewer than the number of
, the lowest-level elements in the remaining
will be used.
