... Analogously, a row vector is an ordered collection of numbers written in a row— that is, a 1 n matrix. We will use boldfaced lowercase letters to represent vectors. Therefore a row vector will be written as z = 3z1 ...

4. Matrices 4.1. Definitions. Definition 4.1.1. A matrix is a rectangular
... Matrices may be added, subtracted, and multiplied, provided their dimensions satisfy certain restrictions. To add or subtract two matrices, the matrices must have the same dimensions. Notice there are two types of multiplication. Scalar multiplication refers to the product of a matrix times a scalar ...

Now that we have the formal definition of a group, our first job is to build a good stock of examples. These examples will be used throughou ...
