Abstract
intpakx is a Maple package for (multiple precision) interval arithmetic. It contains data types, basic arithmetic and standard functions for real interval arithmetic and complex disc arithmetic. Moreover, it implements a handful of algorithms for validated numerical computing and graphical output functions for the visualization of results. The package intpakx thus gives the user the opportunity to do validated computing with a computer algebra system. The package may be used to solve (set valued) numerical problems in a computer algebra environment with mathematical rigor. But it is also a valuable didactical tool which allows the illustration of various interval methods/algorithms. The latest version of intpakX offers the possibility to compute and to visualize the exact solution set of two and three dimensional linear interval systems. This new feature will be discussed in some detail.
