NettetVector Space. A vector space or a linear space is a group of objects called vectors, added collectively and multiplied (“scaled”) by numbers, called scalars. Scalars are usually considered to be real numbers. But there are few cases of scalar multiplication by rational numbers, complex numbers, etc. with vector spaces. NettetThe span of a set of vectors, also called linear span, is the linear space formed by all the vectors that can be written as linear combinations of the vectors belonging to the …

Note on spaces and subspaces (For more details see Strang (2006), p.70) The space of a vector determines all the values that can be taken by this vector. The vector spaces are denoted $\mathbb{R}$ because the values are real numbers.

For example, two linearly independent vectors span a plane. It can be characterized either as the intersection of all linear … Se mer Given a vector space V over a field K, the span of a set S of vectors (not necessarily infinite) is defined to be the intersection W of all subspaces of V that contain S. W is referred to as the subspace spanned by S, or by the vectors in S. … Se mer Equivalence of definitions The set of all linear combinations of a subset S of V, a vector space over K, is the smallest linear subspace of V containing S.
