Example of linear combination
WebSep 17, 2024 · The product of a matrix A by a vector x will be the linear combination of the columns of A using the components of x as weights. If A is an m × n matrix, then x must be an n -dimensional vector, and the product Ax will be an m -dimensional vector. If. A = [v1 v2 … vn], x = [ c1 c2 ⋮ cn], then. Ax = c1v1 + c2v2 + …cnvn.
