Pronunciation: [ˈɪnə pɹˈɒdʌkts] (IPA) 
Inner products are mathematical operations that provide a measure of the similarity between two vectors within a vector space. Synonyms for inner products include scalar products, dot products, and matrix products. Scalar products refer to the multiplication of two vectors to produce a scalar value. Dot products are another way of describing scalar products and derive their name from the dot operator used to denote the operation. Matrix products are a way of representing a collection of inner products between two sets of vectors, where the product is determined by the entries of the matrices.
