Is the inner product the dot product

WitrynaQuestion: 1. Consider real valued functions defined on [−l,l]. Define the inner product (or "dot product") between 2 functions f,g to be f,g =∫−llf (x)g (x)dx (when this integral exists) This in turn, gives, ∥f∥, the norm (or length) of a function f, as ∥f∥2= f,f =∫−llf (x)2dx (when this integral exists) This in turn, gives d ... WitrynaWell, any scalar is an inner product of two vectors. Take arbitrary two nonorthogonal vectors, then their inner product is nonzero, so you can scale one of them (or both) to get the wished scalar.

WitrynaFor the usual case of column vectors, the inner product has the T in between the two operands (as the first operand is transposed), and for the outer product the T is on the second operand so it's "on the outside". But it seems like this is just a superficial mnemonic device and has no relation to the origins of the terminology. – isarandi Witryna20 mar 2024 · Mar 20, 2024 at 23:15 1 The value of the dot product has dimensions square length, so it means nothing without a reference pair of lengths to compare it to (namely the lengths of the original vectors) unless it is zero, because this statement does not depend on a choice of units. – Qiaochu Yuan Mar 20, 2024 at 23:20 Thanks very …
