InnerProduct
Dot (inner, scalar) product of vectors.
Syntax

InnerProduct(u, v)

u
andv
are vectors of the same dimension

Description
If u
and v
are vectors of the same dimension, then InnerProduct(u, v)
is their dot (inner, scalar) product. If both vectors are real, so is InnerProduct(u, v)
. If one or both of the vectors are complex, the complex inner product is used and the result is a complex number (typewise, that is: its imaginary part may well be zero).
Examples
u ≔ ❨1, 0, 1, 1❩/√3; a ≔ ❨1, 5, 2, 1❩;
InnerProduct(a, u)
2.30940107676 (=(4/3)⋅√3)
Notes
The dot (inner, scalar) product between u
and v
can also be written u⋅v
or (uv)
.
The 
operator is implemented by the InnerProduct
function.
