What different between matrix inner product and dot product

Solution

A dot product is technically a term used when discussing the product of 2 vectors is equal to 0.
An inner product is a term used when discussing the integral of the product of 2 functions is equal to 0.

A dot product is a very specific inner product that works and refers to the inner product given by Un..Un...
More generally, an inner product is a function that takes in two vectors and gives a complex number,

Inner product is defined on vector spaces over a field finite or infinite dimensional.
Dot product refers specifically to the product of vectors .
