INTLAB is entirely written in Matlab. It works under Matlab and - to a certain extent - under Octave. INTLAB comprises of
There are a number of demo files for the different INTLAB toolboxes. The demos are not executed, but the results are displayed. You may view the demos directly, or copy the demos directory file into your working directory, change your directory by "cd demos" and call "demointlab".
INTLAB has several thousand users in more than 50 countries and more than 1000 citations in scientific publications. 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. more or less Octave) code to assure best portability. In particular the new ODE toolbox uses Matlab features which are not (yet) supported by Octave; we try to find workarounds. 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.
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. Disclaimer: INTLAB works to a certain extent under Octave. Many main routines work, but not everything, in particular concerning graphics.

INTLAB is thoroughly tested under Windows, Linux and MacOS operating system. It runs under the forthcoming Matlab version R2018b and is downward compatible at least to R2016b.
