## Vectors/Matrices
### example:
column-row syntax: `[1, 2, 3; 4, 5, 6; 7, 8, 9]`
```
⎡1 2 3⎤
⎢4 5 6⎥
⎣7 8 9⎦
```
## Product types:
### Dot-Product (point- or element-wise product)
`a · b` (accepts input: `a * b` and `a b`)
### Tensor-Product (outer product)
`a ⊗ b` (accepts input: `a \x b`)
### Inner-Product
`〈a, b〉` (accepts input: `<a, b>`)
## Functions vs. products
- `f(g)` (no space between) means passing the variable `g` to the function `f`
- `f (g)` (space between) means the dot-product between `f` and `g`
