# Linear Algebra Dot Product

### These properties may be summarized by saying that the dot product is a bilinear form. Linear algebra dot product. Mathematics for machine learning. The dot product defined in this manner is homogeneous under scaling in each variable meaning that for any scalar a it also satisfies a distributive law meaning that. Elements of a vector space may have various nature. The name is derived from the centered dot that is often used to designate this operation. The number returned is dependent on the length of both vectors and on the angle between them.

In mathematics the dot product is an operation that takes two vectors as input and that returns a scalar number as output. Then we look through what vectors and matrices are and. For example they can be sequences functions polynomials or matriceslinear algebra is concerned with properties common to all vector spaces. Definitions of the vector dot product and vector length. This page documents the core linear algebra tools included in dlib.

The dot product is thus characterized geometrically by. Linear algebra from imperial college london. The first four axioms mean that v is an abelian group under addition. In this course on linear algebra we look at what linear algebra is and how it relates to vectors and matrices. In particular the three most important objects in this part of the library are the matrix vector and rectangleall the other tools on this page are functions for manipulating these three objects.
