Go to the first previous next last section, table of contents Linear Combinations Definitions Definition 2.1 Let S be a non-empty subset of V . A vector of the form v=a1v1 + a2v2 + .. +akvk, where ai in R , vi in S, is called a linear combination of elements in S. Notation: The set of linear combinations of elements of S is denoted by S . By convention, we write v1,v2,...,vk instead of Theorem 2.1 S is a subspace. Observ1. if v is in S then S S Observ2. if v is not in S then S is not equal to S S is the smallest subspace containing S, i.e., if S L ,where L is a subspace, then S L. Observ4. If T S then T S Theorem 2.2 Suppse S,T are subsets of V. If T S and S T then S T Proofs A proof of Th2.1 Let u,w be in S . Then we can write u=a1v1 + ... +asvs, w=b1v1 +..+bsvs using some ai or bj = if necessary to make corresponding terms agree. (ai,bj in R and vi in S). u+w = (a1+b1)v1 +...+(as+bs)vs by the commutativity of "+" and the distributive laws.See section Axioms Similarly, ku = (ka1)v1 +...+(kas)vs. A proof of Obsrv1 Enough to show S S . Suppose w= av +a1v1+...+asvs. But v is in S , i.e., v=b1v1+...+bsvs. By substituting, we get w=a(b1v1+... +bsvs)+a1v1+...+asvs and we can regroup it to w=(ab1+a1)v1+...+(abs+as)vs. [again,use some ai,bj = to adjust the common terms].

82. LAPACK An alternative source of LAPACK = linear algebra package, for solving linear equations, SVD and eigenvalues. http://www.cs.colorado.edu/~lapack

Home Help Netlib Search ... Documentation LAPACK Internet Interface and Search Engine LAPACK provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision. Release 3.0 of LAPACK introduces new routines, as well as extending the functionality of existing routines.

88. 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
