it means they are more similar to each other. Similarly, the dot product can be used to calculate the distance between two vectors. 计算两个向量的距离,并用距离来表示两个向量的相似程度 -- 乘积越大,表示越相似。
or a number. The vector dot product can be used to find the angle between two vectors, and to determine perpendicularity. It is also used in other applications of vectors such
1. Dot Product Vectors were based on the intuitive ide a of a directed magnitude, but as yet we have no method to calculate either the magnitudes or the directions of vectors. We now remedy this situation by defining a new vector operation: the dot product. We shall write |v|[1] for ...

The dot product of two vectors is a fundamental operation in linear algebra, and in C++, we can efficiently compute it using the std::inner_product function from the numeric algorithms library.The std::inner_product function is part of the C++ Standard Template Library (STL) and is declared...
Example 1.Find the dot product of vectorsa= {1; 2} andb= {4; 8}. Solution:a·b= 1 · 4 + 2 · 8 = 4 + 16 = 20. Example 2.Find the dot product of vectorsaandb, if their magnitudes is |a| = 3, |b| = 6, and the angle between the vectors is equal to 60˚. ...
In effect, the dot product multiplies the aligned lengths.Remembering CosTo remember to multiply by cos(θ) think "dot cos".Right AnglesWhen two vectors are at right angles to each other the dot product is zero.Example: calculate the dot product for: a· b = |a|× |b|× cos(θ) a...
