Numerical Integration

Since Pn is a linear space, it has a basis. The obvious basis is the set M={1,x,x2,…,xn} of monomials, but it's always convenient to have an orthonormal basis. The Gram-Schmidt process can be used in an inner product space to make a linearly independent set of vectors into an orthonormal set. Let's skip the normalization for now and just look for an orthogonal basis. We start with p0(x)=m0(x)=1
Fields and Charges on a Set

We have known for a long time what the orthogonal complement of a subset S of an inner product space is: S⊥ = {v ∈ V | < u,v >= 0, ∀u ∈ S}. We have enough structure here to define this same concept in a vector lattice setting.

Inner Product (Pre-Hilbert, Unitary) Spaces. A vector space V on which an inner product has been defined is called an inner product space. Sometimes the names pre-Hilbert or unitary spaces are also used for such spaces.

Hence, after the corresponding IMFs are acquired in the EMD process, it is clear that a method that is interested in only orthogonal modes can facilitate the process. As such, the acquired IMFs are processed by the Gram-Schmidt Orthogonalization method to estimate the number of orthogonal components [71]. [72,73] have studied with numeric examples of how all IMFs are not mutually orthogonal. Let V the be a finite-dimensional inner product space, with a basis as a linearly independent subset of V. Then the Gram-Schmidt Orthogonalization process utilize the vectors to construct new vectors , such that for and for i=1,2, … ,n. Algorithm 2 defines, and Figure 2 depicts the Gram-Schmidt Orthogonalization process.
Visualizing the inner product space ℝm×n in a MATLAB-assisted linear algebra classroom
Published in International Journal of Mathematical Education in Science and Technology, 2018
Prelude: This classroom note considers Frobenius inner product – the mapping defined via for real m × n matrices A and B – in a MATLAB-facilitated learning environment. The examples illustrate the defining properties (symmetry, linearity, positive definiteness) of the inner product along with other notions inherent in the inner product space , such as Frobenius norm (length), distance between vectors, angle between vectors, orthogonal projection, Cauchy–Schwarz inequality, triangle inequality, Pythagorean theorem, parallelogram law, orthogonality and orthonormality, orthonormal basis, completeness relation, coordinates relative to an orthonormal basis and Parseval's identity.
