Algebraically, the vector inner product is a multiplication of a row vector by a column vector to obtain a real value scalar provided by formula below Some literature also use symbol to indicate vector inner product because the in the computation, we only perform sum product of the corresponding element and the transpose operator does not really matter.

k cv k=j c jk v k; 2. k v k> 0 if v 6= 0; An inner product on V induces a norm on V corresponding to the inner product, which is a function kk : V !R given by kvk= p (v;v) for v 2V: Basic norm property: kcvk= p (cv;cv) = p c c(v;v) = p jcj2(v;v) = jcjkvk: Also, we call two vectors u;v 2V orthogonal if (u;v) = 0 (as a consequence, by conjugate symmetry, (v;u) = 0 would also hold). The inner product of x and y is a scalar quantity written as x ⋅ y defined by x. y = xTy = [ x1 x2 xn][y1 y2 yn] = x1y1 + x2y2 + + xnyn where xT is the transpose of vector x Properties of the Inner Product If x, y and z are vectors in Rn and k1 and k2 are scalars, then An inner product is a generalization of the dot product. In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar.

Projection. Let’s review something that we may be already familiar with. In the diagram below, we project a vector b onto a. The length x̂ of the projection vector p equals the inner product aᵀb. And p equals Inner Products Generated by Matrices Let be vectors in Rn (expressed as n 1 matrices), and let A be an invertible n n matrix. If u · v is the Euclidean inner product on Rn, then the formula u, v = Au · Av 1 1 2 2and =: : n n u v u v u v u v 2008/12/17 Elementary Linear Algebra 15 defines an inner product; it is called the inner product on Rn Looking for Linear Algebra/Inner Product Space?
