Those totally unfamiliar with linear algebra ... understand most chemometric techniques without a basic understanding of linear algebra. This article reviews the basics of linear algebra and provides the reader with the foundation required for understanding ... the vectors are linearly independent. Otherwise, at least one of the vectors is a linear combination of the other vectors and they are linearly dependent. It is easy to visualize linear independence....
