Lesson 12-1
... A matrix is a rectangular arrangement of data in rows and columns. You identify the size of a matrix by the number of row and the number of columns. So for the following matrix it would be a 3 x 2 because it has 3 rows and 2 columns. ...

... An algebra A is commutative if a · b = b · a. Usually commutative algebras are supposed to be associative as well. 1.1.2. Example If V is a vector space, End(V ), the set of (linear) endomorphisms of V is an associative algebra with respect to composition. If V = k n End(V ) is just the algebra of n ...
