Norm of product of two vectors

WebLIP-2.The inner product of vectors X and Y in Rn is, by definition, hX,Yi:=x1y1 +x2y2 +···+xnyn. (1) This is also called the dot product and written X ·Y . The inner product of two vectors is a number, not another vector. In particular, we have the vital identity kXk2 =hX,Xi relating the inner product and norm. Web24 de mar. de 2024 · The -norm of vector is implemented as Norm [ v , p ], with the 2-norm being returned by Norm [ v ]. The special case is defined as (3) The most commonly encountered vector norm (often simply called "the norm" of a vector, or sometimes the magnitude of a vector) is the L2-norm , given by (4)
