Eigenvalue analysis of non-hermitian matrices and operators can be misleading: Predictions often fail to match observations. Specifically, trouble may arise when the associated sets of eigenvectors are ill-conditioned with respect to the norm of applied interest. In the case of the familiar Euclidean or 2-norm, this means that the matrix or operator is non-normal , and the eigenvectors are not orthogonal. Pseudospectra provide an analytical and graphical alternative for investigating non-normal matrices and operators.

Abstract linear spaces Algebra index History Topics Index Version for printing Cartesian geometry, introduced by Fermat and Descartes around 1636, had a very large influence on mathematics bringing algebraic methods into geometry. By the middle of the 19 th Century however there was some dissatisfaction with these coordinate methods and people began to search for direct methods, i.e. methods of synthetic geometry which were coordinate free. It is possible however to trace the beginning of the vector concept back to the beginning of the 19 th Century with the work of Bolzano . In 1804 he published a work on the foundations of elementary geometry Bolzano , in this book, considers points, lines and planes as undefined elements and defines operations on them. This is an important step in the axiomatisation of geometry and an early move towards the necessary abstraction for the concept of a linear space to arise. The move away from coordinate geometry was mainly due to the work of Poncelet and Chasles who were the founders of synthetic geometry. The parallel development in analysis was to move from spaces of concrete objects such as sequence spaces towards abstract linear spaces. Instead of substitutions defined by matrices, abstract linear operators must be defined on abstract linear spaces. In 1827 published Der barycentrische Calcul a geometrical book which studies transformations of lines and conics. The novel feature of this work is the introduction of barycentric coordinates. Given any triangle

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.

smart BLAP95 This software is a Fortran 95 interface to the Level 3 BLAS routines and key LAPACK computational and driver routines. It supersedes the older smart BLAS95 package. Please note that the interfaces are still under development. Bug reports are appreciated. This software differs from other implementations, (such as , the F95 blas proposal by Zohair Maany and Sven Hammarling or Intel MKL ) in the following: It aims to exploit the INC* and LD* arguments in the F77 BLAS and LAPACK routines to deal with noncontiguous arrays, avoiding a copy-in-copy-out if possible. This cannot, however, be achieved by means of standard Fortran, which hides the memory layout. For this purpose the interface uses one non-standard intrinsic function, loc . This is provided as an extension by a number of compilers, including gfortran,g95, Intel, Lahey, Portland and PathScale. (If you know about a compiler not listed here, please email me). Alternatively, external LOC coded in C may be used. The bytesizes for Fortran types are specified directly in the m4 sources and can be altered if necessary. Currently, the following packages are available:
