Overview

This is week two (of three) where we continue our review of linear algebra. We will be focusing on methods to summarize information in a matrix as well as an initial introduction to elementary row operations.

Objectives

At the conclusion of this chapter and the assocaiated assignment, you will be able to:

• compute the determinant and trace of arbitrarily large matrices;
• identify uses of the trace and determinant in spatial econometrics;
• generate augmented matrices suitable for a number of applications, including solving systems of linear operations;
• apply elementary row operations;
• compute a matrix inversion.
