The above example is a somewhat exaggerated example of contractions. In both cases 'every' is used to force all alternatives including row labels, column headings, content, line terminators. The upper triangle is produced by embedding an 'if' expression inside the object of an 'every' (normally an error prone construct which would malfunction if not |
The above example is a somewhat exaggerated example of contractions. In both cases 'every' is used to force all alternatives including row labels, column headings, content, line terminators. The upper triangle is produced by embedding an 'if' expression inside the object of an 'every' (normally an error prone construct which would malfunction if not carefully separated from the generators for 'i' and 'j' - an all too tempting possibility once you get into this mind set.) |
