	Orthonormality - Wikipedia, the free encyclopedia
		In linear algebra, two vectors v and w in an inner product space are said to be orthonormal if they are orthogonal and of unit length (that is, their inner product is zero and the norm of each of them is 1).
		A set of vectors which are pairwise orthonormal is called an orthonormal set.
		A basis which forms an orthonormal set is called an orthonormal basis.

	Basis (linear algebra)
		S is both a set of linearly independent vectors and a generating set of V.
		Recall that a set S is a generating set of V if every vector in V is a linear combination of vectors in S.
		An orthonormal basis of a Hilbert space H is an orthonormal set of members of H such that any member of the H can be written as a linear combination of a possibly infinite set of members of the orthonormal basis.

	Hilbert space - Wikipedia, the free encyclopedia
		This problem can be studied abstractly in Hilbert spaces: every Hilbert space has an orthonormal basis, and every element of the Hilbert space can be written in a unique way as a sum of multiples of these base elements.
		Note that in the infinite-dimensional case, an orthonormal basis will not be a basis in the sense of linear algebra; to distinguish the two, the latter basis is also called a Hamel basis.
		The set L(H) of all continuous linear operators on H, together with the addition and composition operations, the norm and the adjoint operation, forms a C

		Given a set of three points defined in a cartesian coordinate system, and the desired set of coordinates for those same three points, determine the translation and rotation needed to perform the desired transform (scaling is not allowed).
		Generate a set of orthonormal basis vectors from three points given in cartesian coordinates.

	III. Fourier series, Introduction
		As mentioned in the previous section, perhaps the most important set of orthonormal functions is the set of sines and cosines (2.8).
		It is a theorem that each of the sets of trigonometric functions (2.6)-(2.9) is complete and orthonormal, but the techniques for proving such a theorem are beyond the scope of this course.
		Since each of the functions in the set is periodic with period L, any linear combination of them is also periodic with the same period.

		Then any orthonormal subset T of G will meet the sum of E2 and E3 only in E3, and hence the projection of T to E2 will be countable; but the projection of G onto E2 has dense image.

		Let H_2 be the non-separable Hilbert space with orthonormal basis {y_b: b in B} indexed by B. Let K be the linear span of the vectors {x_b + y_b: b in B} in the direct sum H_1 + H_2.

		This one is the basis of the usual Fourier series, and is perhaps the most important of all our orthonormal sets.
		It is often convenient to have orthonormal, or at least orthogonal sets.
		Although we shall first concentrate on the set (2.8) as a basis for a vector space of functions, the other sets of orthonormal functions (2.5)-(2.7) and (2.9) will be useful later for the same purpose.

		A linear operator applied successively to the members of an orthonormal basis may give a new set of vectors which no longer span the entire space.
		From the above, the set of powers of an Hermitian matrix all commute with each other, and have a common set of eigenvectors (but not the same eigenvalues, obviously).
		As previously stated, a unitary matrix is an operator that rotates an orthonormal basis into another orthonormal basis.

		This may seem odd given that we call the matrix “orthogonal” when “orthonormal” would probably be a better name for the matrix, but traditionally this kind of matrix has been called orthogonal and so we’ll keep up with tradition.

	Orthogonality and Least Squares (Site not responding. Last check: 2007-10-23)
		The idea is, of course, that orthogonal bases are much easier to work with and lend themselves nicely to performing various computations such as finding vector coordinates with respect to this basis and projecting vectors on various subspaces of a vector space.
		Closely tied to this idea is the concept of orthogonal matrices: square matrices whose columns form an orthonormal set.
