WebDot product not a binary operation, associativity doesn't even make sense. – spaceisdarkgreen Jan 11, 2024 at 1:26 In general, for an inner-product space ( V, ⋅, ⋅ ), over a field F, the inner product is a function V × V → F, whereas a binary operation on V … WebVectorized "dot" operators. For every binary operation like ^, there is a corresponding "dot" operation .^ that is automatically defined to perform ^ element-by-element on arrays. For example, [1,2,3] ^ 3 is not defined, since there is no standard mathematical meaning to "cubing" a (non-square) array, but [1,2,3] .^ 3 is defined as computing the elementwise …
