Unification of System of Linear Equations, Matrix Inversion, and Linear Programming Europe Mirror Site Mirror Site for Asia Mirror Site for Middle East USA Site This site extends the existing one-way connections among the solving linear systems of equations, matrix inversion, and linear programming. The additional linkages empower the user to understand the wholeness and manifoldness of these topics. They also assist the user to model and solve a problem modeled as any one of the above topics by having access to a computer package solver. The goals are theoretical unification as well as advancements in applications. Illustrative numerical examples are presented.

USA Site Introduction Linear programming (LP), Linear systems of equations, and Matrix inversion are often favorite topics for both instructors and students. The ability to solve these problems by Gauss-Jordan pivoting (GJP), the widespread availability of software packages, and their wide range of applications make these topics accessible even for students with relatively weak mathematical backgrounds. The typical textbooks on LP usually devote separate sections for each topic. However, the relationships among these closely related topics are often not presented or thoroughly discussed. This article extends the existing one-way connections among these topics to construct a comprehensive two-way relationship as in the following figure. For each topic, it is shown how the problem may be modeled and solved by either of the associated methodologies.

164. Abu Ja'far Al-Khwarizmi Arab mathematician, lived when spread of ideas was very slow, wrote Hisab aljabr wal-muqabala, concepts of the Middle East. The al-jabr gave us the word algebra. introduced the decimal system, rules for solving linear and quadratic equations, the word algorithm comes from his name. http://www.windows.ucar.edu/people/middle_ages/al-khwarizmi.html

Abu Ja'far al-Khwarizmi Abu Ja'far al-Khwarizmi was an Arab mathematician who lived between AD 780 and 850. At a time when the spread of ideas was difficult, al-Khwarizmi wrote a book which contained many important mathematical concepts of the Middle East. This book changed all of European mathematics, introducing the decimal system and rules for doing algebra.

168. MOHAMMAD BIN MUSA AL-KHAWARIZMI,great Muslims,great Moslems,famous Muslims,famou Was one of the first people to work on algebra solutions in a systematic way for linear and algebraic solutions. Is attributed in this article to discovering the properties of zero and the decimal systems, as well as other major contributions. http://www.famousmuslims.com/MOHAMMAD BIN MUSA AL-KHAWARIZMI.htm

Home Page Scientists One of the Greatest Mathematicians: MOHAMMAD BIN MUSA AL-KHAWARIZMI Abu Abdullah Mohammad Ibn Musa al-Khawarizmi was born at Khawarizm (Kheva), south of Aral sea. Very little is known about his early life, except for the fact that his parents had migrated to a place south of Baghdad. The exact dates of his birth and death are also not known, but it is established that he flourished under Al- Mamun at Baghdad through 813-833 and probably died around 840 C.E. Khawarizmi was a mathematician, astronomer and geographer. He was perhaps one of the greatest mathematicians who ever lived, as, in fact, he was the founder of several branches and basic concepts of mathematics. In the words of Phillip Hitti, he influenced mathematical thought to a greater extent than any other medieval writer. His work on algebra was outstanding, as he not only initiated the subject in a systematic form but he also developed it to the extent of giving analytical solutions of linear and quadratic equations, which established him as the founder of Algebra. The very name Algebra has been derived from his famous book Al-Jabr wa-al-Muqabilah The development of astronomical tables by him was a significant contribution to the science of astronomy, on which he also wrote a book. The contribution of Khawarizmi to geography is also outstanding, in that not only did he revise Ptolemy's views on geography, but also corrected them in detail as well as his map of the world. His other contributions include original work related to clocks, sundials and astrolabes.
