Outer

FilledSmallSquareOuter[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.

FilledSmallSquareOuter[f, , , ... , n] treats as separate elements only sublists at level n in the .

FilledSmallSquareOuter[f, , , ... , , , ... ] treats as separate elements only sublists at level in the corresponding .

FilledSmallSquare Example: Outer[f,a,b,x,y] LongRightArrow.

FilledSmallSquareOuter[Times, , ] gives an outer product.

FilledSmallSquare The result of applying Outer to the tensors and is the tensor with elements f[,]. Applying Outer to two tensors of ranks and gives a tensor of rank .

FilledSmallSquare The heads of both must be the same, but need not necessarily be List.

FilledSmallSquare The need not necessarily be cuboidal arrays.

FilledSmallSquare The specifications of levels must be integers.

FilledSmallSquare 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 , all levels in the remaining will be used.

FilledSmallSquare See The Mathematica Book: Section 1.8.15, Section 2.2.10, Section 3.7.5 and Section 3.7.11.
