# torch dot product

• ### Tensor Notation (Basics)Continuum Mechanics

· The dot product of two matrices multiplies each row of the first by each column of the second. Products are often written with a dot in matrix notation as $${\bf A} \cdot {\bf B}$$, but sometimes written without the dot as $${\bf A} {\bf B}$$. Multiplication rules are in fact best explained through tensor notation.

· Comparators¶. The available comparators are dot, the dot-product, which computes the scalar or inner product of the two embedding vectors cos, the cos distance, which is the cosine of the angle between the two vectors or, equivalently, the dot product divided by the product of the vectors’ norms. l2, the negative L2 distance, a.k.a. the Euclidean distance (negative because smaller
