Biochemical Basis of Herbicide Resistance,In order to proceed further with matrices we have to take a wider view of matters. This we do through the following important notion.

Biochemical Basis of Herbicide Resistance,In the study of any algebraic structure there are two concepts that are of paramount importance. The first is that of a . (i.e. a subset with the same type of structure), and the second is that of a . (i.e. a mapping from one structure to another of the same kind that is ‘structure-preserving’).

https://doi.org/10.1007/978-3-642-79107-9We shall now proceed to show how a linear mapping from one finite-dimensional vector space to another can be represented by a matrix. For this purpose, we require the following notion.
