9 Inner product - Auburn University

An innerproductspaceis a vector space with an inner product. Each of the vector spaces Rn, Mm×n, Pn, and FI is an inner product space: 9.3 Example: Euclidean space We get an inner product on Rn by deﬁning, for x,y∈ Rn, hx,yi = xT y. To verify that this is an inner product, one needs to show that all four properties hold. We check only two ...

NOTES ON DUAL SPACES - Northwestern University

These last few results in particular show the sense in which dual spaces can be used to rephrase many notions coming from inner products without actually using inner products. This can be quite useful for the following reason: choosing an inner product involves making

be regarded as metric spaces with respect to the metric d. A normed space is called a Banach space if it is complete with respect to the metric d. Definition. Let Xbe a linear space over K (=R or C). The inner product (scalar product) is a function h·,·i: X×X→K such that (1) hx,xi≥0; (2) hx,xi= 0 if and only if x= 0; (3) hαx,yi= αhx,yi ...

1 Inner products and norms - Princeton University

The standard inner product between matrices is hX;Yi= Tr(XTY) = X i X j X ijY ij where X;Y 2Rm n. Notation: Here, Rm nis the space of real m nmatrices. Tr(Z) is the trace of a real square matrix Z, i.e., Tr(Z) = P i Z ii. Note: The matrix inner product is the same as our original inner product between two vectors
