## DOT Dot Product Function

Section: Elementary Functions

### Usage

Computes the scalar dot product of its two arguments. The general syntax for its use isy = dot(x,z)

where `x`

and `z`

are numerical vectors of the same length. If
`x`

and `z`

are multi-dimensional arrays of the same size, then
the dot product is taken along the first non-singleton dimension.
You can also specify the dimension to take the dot product along using
the alternate form

y = dot(x,z,dim)

where `dim`

specifies the dimension to take the dot product along.
