Linear algebra: applications

This chapter discusses applications of matrix algebra to illustrate techniques

developed earlier. Section 3.2 reviews the basic supply and demand model with

two goods. Sections 3.4 to 3.7 consider various applications, illustrating tech-

niques such as the use of matrix polynomials and convergence of matrix expan-

sions. These techniques have widespread use (for example in the study of dynamic

systems) and are developed further in later chapters.
