Duality,ected in the mathematical models of those systems. Since problems of linear programming are frequently derived from economic systems the duality exhibited by the general LP problem is the mathematical expression of the underlying economic duality.

https://doi.org/10.1007/978-981-19-5149-7 where each linear problem requires the solution of one or more sets of linear equations for its own resolution. It is thus highly desirable to have at our disposal a good method for solving a general set of linear equations, with perhaps one or two special methods for use when the matrix of coefficients A exhibits special properties.

,Introduction — the Tools of the Trade,cts, all different, but all sharing some common property or properties. We might, for example, be engineers measuring the power of an engine and finding how this varies with throttle setting, mixture control and ignition timing. These three adjustments, whose effect on the internal state of the engi

Matrix and Vector Norms,ors and matrices, that of ‘size’ or ‘magnitude’. We often want to be able to say that one vector is, in some sense, ‘bigger’ than another. In particular, if we have a sequence of vectors, it is sometimes useful to know that these vectors are getting ‘smaller’. This would certainly be the case if eac
