That's a cartesian product, not a tensor product.

That's a cartesian product, not a tensor product.
- acjohnson55 13y agoI think it might be a bit more correct to call it the outer product.
- mrcactu5 13y agothe outer product is the tensor product of two vectors https://en.wikipedia.org/wiki/Outer_product https://en.wikipedia.org/wiki/Outer_product
- bsaul 13y agoCould that be the start of an introduction to tensor products or even tensors in general ? Start with cartesian product ( or maybe even sql joins ? ) and generalize ? It's probably much more intuitive to us developpers than vector products ( unless you're in 3D graphics or physic engine of course )
