|Paypal is a very simple method for international money transfer. If this is difficult for you, please drop me a mail. In that case I send you an invoice with account number.|
To obtain INTLAB, please press the corresponding link below which will lead you to a paypal-site. After payment you find a link for downloading INTLAB for Windows, or Linux and Mac. Note that the download is open for one hour.
In any case you receive an e-mail with a paypal-receipt and again the download-link. If you need another kind of invoice, please contact me at rump∂tuhh.de.
The license allows you run INTLAB at work and at home on your personal computer; only remember that, unless other agreements apply, it is a personal copy.
Since the first version in 1999, INTLAB has been constantly developed and improved. I designed and wrote all of INTLAB, and since the beginning I put my knowledge of verification methods into INTLAB.
INTLAB has been used as the computational basis for several hundred publications (cf. selected refences), and often I have to answer queries by the many thousand users. It was always free for academic use.
The development and support of INTLAB is taking a substantial amount of my time, so that I decided to ask for a small appreciation for me and my institute. If you like INTLAB and find it useful, you may obtain a personal copy for research and development as an Academic User or Non-Academic User. Here "academic" is defined as a "degree granting institution". Companies associated with universities do not qualify.
In any case INTLAB shall not be part of a commercial program which requires INTLAB or part of INTLAB to run properly. If you intend to do that, please contact me under rump∂tuhh.de.
Since Version 9 there is one version of INTLAB. It works with Matlab and Octave, and on all operating systems (Windows, Linux, MacOS), both 32- and 64-bit.
INTLAB is entirely written in Matlab. It works under Matlab and Octave. INTLAB comprises of
There are a number of demo files for the different INTLAB toolboxes. Matlab/Octave demos are not executed, but the results are displayed. You may view the demos directly, or copy the demos directory file into your Matlab/Octave working directory, change your directory by "cd demos" and call "demointlab".
INTLAB has several thousand users in more than 50 countries. INTLAB is used in many areas, from verification of chaos to population biology, from controller design to computer-assisted proofs, from PDEs to Petri Nets (cf. some selected Refences to INTLAB). Over the years many colleagues helped to improve INTLAB, my dearest thanks to them!
The main focus of INTLAB is to produce reliable results. Any result is proved to be true under any circumstances, in particular covering rounding errors and all error terms. The other main focus is to be fast.
The philosophy of INTLAB is that everything is written in Matlab (i.e. Octave) code to assure best portability. Interval vector and matrix operations are very fast due to extensive use of BLAS routines. However, nonlinear computations and loops may slow down the system significantly due to interpretation overhead and extensive use of the operator concept.
Details and examples about timing can be found here. Moreover, some routines treat extremely ill-conditioned problems. Details and examples are here.Further reading
Most routines in INTLAB are self-explaining and/or information can be obtained by the Matlab/Octave help command (cf. also readme.txt for more information). For download and installation under Octave see here.

INTLAB is thoroughly tested under Windows, Linux and MacOS operating system.
