It's some combination of a sum of the vectors, so v1 plus v2 plus all the way to vn, but you scale them by arbitrary constants. So you scale them by c1, c2, all the way to cn, where everything from c1 to cn are all a member of the real numbers.

WebC [a]b = a is the equation for a change of basis. A basis, by definition, must span the entire vector space it's a basis of. C is the change of basis matrix, and a is a member of the vector space. In other words, you can't multiply a vector that doesn't belong to the span of v1 and v2 by the change of basis matrix. hills search

WebSep 16, 2024 · Definition 4.11.1: Span of a Set of Vectors and Subspace. The collection of all linear combinations of a set of vectors {→u1, ⋯, →uk} in Rn is known as the span of these vectors and is written as span{→u1, ⋯, →uk}.
