""Matrices, Elimination And The Simplex Method"" by William Orchard-Hays is a comprehensive guide to the mathematical concepts of matrices and elimination, as well as the simplex method. The book provides a detailed explanation of the fundamental principles of matrix algebra and the various techniques of matrix manipulation. It also covers the process of elimination, which is an essential tool for solving systems of linear equations.The book goes on to explore the simplex method, which is a powerful optimization technique used in linear programming. The author explains the simplex algorithm in a clear and concise manner, providing numerous examples and practical applications to illustrate its use. The book also covers the duality theorem, sensitivity analysis, and other important topics related to linear programming.Overall, ""Matrices, Elimination And The Simplex Method"" is an excellent resource for students and professionals in the fields of mathematics, engineering, and economics who are looking to deepen their understanding of linear algebra and optimization techniques. The book is written in a clear and accessible style, making it easy to follow even for those without a strong background in mathematics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
