Hi,

How can i make the tensor product (producto tensorial) between 2 vectors.

Because i can only find dot product and cross product.

That is potentially a three step process.
1. decide how you want to represent your tensor
2. code a function that performs the product
3. use infix notation (xfy) in the bulk of the sheet
(Using the literal notation (ctrl+shift+K) to allow
the use of special characters e.g. *, dot, ...) [use
cut and paste to replicate where required, it's
quicker than typing]

[the problem is that general tensors are not that
common in everyday maths, so there isn't an accepted
notation - is a matrix just a vector tensor, or
should we use a vector of vectors for that tensor]
