A number of sample Mathematica programs, implementing the different approaches for one- and two-dimensional examples, are discussed. Apart from small examples, the corresponding programs are not contained in the text, but will be made available in electronic form.18 pages, lots of figures; tutorial introduction prepared for a summer school on quasicrystals held in Chemnitz 1997; will eventually be published as part of a book on "Quasicrystals"; see also math-ph/9901014Materials ScienceDisordered Systems and Neural Networkstext
