DOT Dot Product Function

Section: Elementary Functions

Usage

Computes the scalar dot product of its two arguments. The general syntax for its use is 
  y = 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.
