The Control and Systems Library SLICOT General information The freeware subroutine library SLICOT provides Fortran 77 implementations of numerical algorithms for computations in systems and control theory. Based on numerical linear algebra routines from BLAS and LAPACK libraries, SLICOT provides methods for the design and analysis of control systems. The basic ideas behind the library are: 1. usefulness of algorithms; 2. robustness, algorithms must either return reliable results or an error or warning indicator; numerical stability and accuracy: the results are as good as can be expected when working at a given precision. If possible an estimate of the achieved accuracy should be given; performance with respect to speed and memory requirements. Although important because of ever increasing complexity of control problems, this objective may never be met at cost of the two previous ones; 5. portability and reusability the library should be independent of platforms; standardisation based on rigorous programming and documentation standards;

ABOUT: Introduction History Related areas Subfields POINTERS: Texts Software Web links Selected topics here 15: Linear and multilinear algebra; matrix theory (finite and infinite) Introduction Linear algebra, sometimes disguised as matrix theory, considers sets and functions which preserve linear structure. In practice this includes a very wide portion of mathematics! Thus linear algebra includes axiomatic treatments, computational matters, algebraic structures, and even parts of geometry; moreover, it provides tools used for analyzing differential equations, statistical processes, and even physical phenomena. History See for example the Vector space and Matrix theory pages from the St. Andrews History files. Here is a paper on Hermann Grassmann and the Creation of Linear Algebra . Further reading: T.L.

91. Introduction To Translation Of Grassmann's Ausdehnungslehre Explains the published paper called Ausdehnungslehre, which translates to Theory of Extension . The purpose is to create a universal type of geometric calculus. This development is used in linear and nonlinear algebra, today. http://www.maths.utas.edu.au/People/dfs/Papers/GrassmannTranslation/node3.html

NEXT PAGE CONTENTS PREVIOUS PAGE Introduction Hermann Grassmann's 1862 Ausdehnungslehre (literally, ``Theory of Extension'') is one of the great mathematical works of the nineteenth century. In it the foundations of linear and multilinear algebra are laid and much of the superstructure too is constructed. It is regrettable that such a book on such a subject should, from the moment of publication, have been not much read. Indeed, Grassmann's reputation for impenetrability has persisted to this day. Yet one may suspect that a writer who is, in many respects, a century ahead of his time will be somewhat more readable when that century has elapsed than he was to his contemporaries. It is my hope that this translation and commentary will make it easy for today's mathematically educated reader to appreciate Grassmann's presentation of the theory of basis and dimension - it does not differ much from the initial chapter of a modern linear algebra text. The work called simply Die Ausdehnungslehre , though its title page bears the date 1862, actually appeared in the latter half of 1861. It was Grassmann's second attempt to present his theory and was totally different in conception from

Linear Algebra Done Right second edition (1997), eighth corrected printing (2005) Sheldon Axler This text, published by Springer, is intended for a second course in linear algebra. The novel approach used throughout the book takes great care to motivate concepts and simplify proofs. For example, the book presents, without having defined determinants, a clean proof that every linear operator on a finite-dimensional complex vector space (or on an odd-dimensional real vector space) has an eigenvalue. Although this text is intended for a second course in linear algebra, there are no prerequisites other than appropriate mathematical maturity. Thus the book starts by discussing vector spaces, linear independence, span, basis, and dimension. Students are introduced to inner-product spaces in the first half of the book and shortly thereafter to the finite-dimensional spectral theorem. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. Excerpts from Reviews Altogether, the text is a didactic masterpiece.

INTRODUCTION I have taught very successfully without a computer lab, in fact, with a minimum of equipment, by assigning projects as group work. A surprising number of students own some version of Maple. Group work speeds up the learning and also the grading, but it occasionally brings up its own problems. Guidelines for what is considered legitimate and healthy cooperation sometimes must be explained.
