matlab区间计算包，可用于区间运算

A short overview how to use INTLAB (see also file FAQ): ======================================================= I started to develop INTLAB with the introduction of the operator concept into Matlab. It is continuously developed since the first version in 1998. The inventor and only developer is Siegfried M. Rump, head of the Institute for Reliable Computing at the Hamburg University of Technology. In any publication or other material using INTLAB please cite S.M. Rump: INTLAB - INTerval LABoratory. In Tibor Csendes, editor, Developments in Reliable Computing, pages 77-104. Kluwer Academic Publishers, Dordrecht, 1999. @incollection{Ru99a, author = {Rump, {S.M.}}, title = {{INTLAB - INTerval LABoratory}}, editor = {Tibor Csendes}, booktitle = {{Developments~in~Reliable Computing}}, publisher = {Kluwer Academic Publishers}, address = {Dordrecht}, pages = {77--104}, year = {1999}, url = {http://www.ti3.tuhh.de/rump/} } ***** INSTALLATION ***** The easiest way to start is create a file startup.m (or to replace the content of the existing one) in the Matlab path \toolbox\local by cd ... insert the INTLAB path ... startintlab Then the startintlab.m file is started and should do the rest. For some user-specific options you may adjust the file startintlab.m . For Octave, download the current version from the net or from my homepage. For Octave the routine "setround" for changing the rounding mode is generated automatically. The Octave people do indeed an amazing job. Note, however, that it is a non-commercial enterprise, so bare with little inconveniences. In any case, the Octave people are very eager to fix possible bugs. ********************************************************************************** The documentation is included in every routine. INTLAB-code, i.e. Matlab-code, is (hopefully) self-explaining. INTLAB stays to the philosophy to implement everything in Matlab. INTLAB is successfully tested under several Matlab versions, starting with version 5.3 until to date. INTLAB is entirely written in Matlab. There is no system dependency. This is because the Mathworks company was so kind to add into the routine "system_dependent" a possibility to change the rounding mode (my dear thanks to Cleve). The progress in the different INTLAB versions can be viewed using help, for example help INTLAB_version_10 INTLAB supports - interval scalars, vectors and matrices, real and complex, - full and sparse matrices, - interval standard functions, real and complex, - and a number of toolboxes for intervals, affine arithmetic, gradients, hessians, taylor, fl-type, slopes, polynomials, multi-precision arithmetic and more. There are several demo-routines to get acquainted with INTLAB, please enter demo toolbox intlab . INTLAB results are verified to be correct including I/O and standard functions. For the homo ludens in you, try intlablogo . If you have comments, suggestions, found bugs or similar, contact rump(at) tuhh.de . DISCLAIMER: Extensive tests have been performed to ensure reliability =========== of the algorithms. However, neither an error-free processor nor an error-free program can be guaranteed. INTLAB LICENSE INFORMATION ========================== Copyright (c) 1998 - 2017 Siegfried M. Rump Institute for Scientific Computing Hamburg University of Technology Germany All rights reserved. ===> There are three ways to use INTLAB: 1) Private or academic use, where "academic" means working in a degree granting institution. Research laboratories with no degree program are considered "industrial." Companies associated with universities do not qualify. 2) Industrial use for research and development, where INTLAB or parts of INTLAB are not part of any product. 3) Industrial use for research and development such that INTLAB or parts of INTLAB are necessary for a product to work properly. In case 1) and 2) there is a one-time charge. This is for one individual to use INTLAB unlimited time. In case 3) an explicit license is required, please contact me rump[at]tuhh.de . In any case, proper acknowledgement is required that INTLAB has been developed by Siegfried M. Rump, head of the Institute for Scientific Computing at the Hamburg University of Technology, Germany.
