hi, i want to work with a data structure which is basically a tensor product or matrix of matrixes of vectors. so for instance, i'd like to do operations like taking an i x j matrix of 3 vectors and an n x n matrix of 3 vectors, and form the (i x j) x (n x n) matrix of dot products. it would appear that Outer, Flatten, List etc are exactly set up to do this sort of thing but i can't seem to get the hang of it. is there a good introduction, or overview (rather than function by function) documentation, or illustrative examples of this? thanks in advance!
