Key Concepts

Orthogonal Basis

An orthogonal basis is a set of vectors in an inner product space where every pair of distinct vectors is orthogonal (their inner product is zero). This property simplifies many computations in linear algebra, such as projections and decompositions, because the coefficients in expressions involving these vectors can be computed directly using the inner products.

Subspace and Span

A subspace is a subset of a vector space that is closed under addition and scalar multiplication. The span of a set of vectors is the collection of all linear combinations of those vectors, forming a subspace. Identifying the subspace spanned by a set of vectors is the first step in many processes, such as finding bases.

Gram-Schmidt Process

The Gram-Schmidt process is an algorithm used to convert a set of linearly independent vectors in an inner product space into an orthogonal (or orthonormal) set of vectors that span the same subspace. This process is fundamental for constructing orthogonal bases, which simplifies many problems in numerical methods and theoretical applications.

Linear Independence

Linear independence is a key concept in determining a basis for a subspace. A set of vectors is linearly independent if no vector in the set can be written as a linear combination of the others. Ensuring linear independence is essential when forming a basis because it guarantees that the basis vectors collectively provide the minimal spanning set for the space.
