Vectors are mathematical objects that have both magnitude and direction. The magnitude, also known as the norm, is the length of the vector, while the direction is the angle it makes with a fixed reference axis. Normalizing a vector means scaling it to have a unit norm, or length of one. This process is useful … Read more
