Expert Solution
Step 1 Introduction

Standard matrix for the linear transformation T :

Let T : nm be a linear transformation. Then there exists a unique m×n matrix A such that 

                                  T(x)=Ax for all x in n.

In fact, A is the matrix whose jth column is the vector T(ej), with ejn:

                      A = [ T(e1) T(e2) T(e3)   T(en) ]

The matrix A is called standard matrix for the linear transformation T .
