What is the definition of an inner product space?
An inner product space is a normed vector space where the inner product of a vector with itself is real and positive-definite.
How is the dot product defined for vectors?
The dot product is defined for vectors that have a finite number of entries.
What is the Frobenius inner product and how is it defined?
The Frobenius inner product is analogous to the dot product on vectors and is defined as the sum of the products of the corresponding components of two matrices.
