In some programming languages, given a two-argument function f (or a binary operator), the outer product of f and two one-dimensional arrays A and B is a two-dimensional array C such that C = f(A, B). e.g., 42 for properties of these operators. In MATLAB we use dot function to get the dot product of scalars or vectors. This shows why a conjugate transpose of v is commonly taken in the complex case. The Hadamard (elementwise) product of matrices A and B is denoted by A B. 1.3 Connection with the Kronecker product.Invoking a unit circle would restrict dot products to unit vectors.

If you draw a diagram and calculate the projected length of the shorter onto the longer vector, it goes as cosine of the angle by elementary trigonometry. There is a different definition when you work with complex vectors.

The operation used were commutative it does not matter in which order the operation is performed.

1.1 Contrast with Euclidean inner product It is because the dot product is the projection of one vector onto another. The dot product of two vectors is determined by multiplying their x -coordinates, then multiplying their y -coordinates, and finally adding the two products.
