矩阵与方程组 矩阵与方程组的英文版 Probably the most important problem in mathematics is that of solving a system of linear equations. Well over 75 percent of all mathematical problems encoun¬tered in scientific or industrial applications involve solving a linear system at some stage. By using the methods of modem mathematics, it is often possible to take a sophisticated problem and reduce it to a single system of linear equations. Lin¬ear systems arise in applications to such areas as business, economics, sociology, ecology, demography, genetics, electronics, engineering, and physics. Therefore, it seems appropriate to begin this book with a section on linear systems.
