Elements of Numerical Linear Algebra
In this chapter, we will consider the problems of solving a system of linear
equations and computing eigenvalues of a matrix. These problems arise in
many important applications, such as polynomial interpolation, solution of
ordinary differential equations, numerical optimization and others.
Example 3.1 Suppose that a company is planning to invest the total of $1
million into three projects, A, B, and C. The estimated one-year returns for
each project under two different market conditions (scenarios), I and II, are
summarized in Table 3.1.
