Show the rules for an FIS structure in verbose, symbolic, or indexed format. Built in languages for the ’verbose’ format are: English, Chinese (or Mandarin, Pinyin), Russian (or Pycckii, Russkij), French (or Francais), Spanish (or Espanol), and German (or Deutsch). The names of the languages are case-insensitive, Chinese is written in Pinyin, and Russian is transliterated.
To use a custom language, enter ’verbose’ and ’custom’ for the third and fourth parameters, respectively, and a cell array of ten strings (to specify the custom language) corresponding to the English {"and" "or" "If" "then" "is" "isn’t" "somewhat" "very" "extremely" "very very"} for the fifth parameter.
To run the demonstration code, type demo('showrule') at the Octave prompt.

The following code
fis = readfis ('sugeno_tip_calculator.fis');
puts ("Output of: showrule(fis)\n");
showrule (fis)
puts ("\n");
Produces the following output
Output of: showrule(fis) 1. If (Food-Quality is extremely Bad) and (Service is extremely Bad), then (Cheap-Tip is extremely Low) and (Average-Tip is very Low) and (Generous-Tip is Low) (1) 2. If (Food-Quality is Good) and (Service is extremely Bad), then (Cheap-Tip is Low) and (Average-Tip is Low) and (Generous-Tip is Medium) (1) 3. If (Food-Quality is very Good) and (Service is very Bad), then (Cheap-Tip is Low) and (Average-Tip is Medium) and (Generous-Tip is High) (1) 4. If (Food-Quality is Bad) and (Service is Bad), then (Cheap-Tip is Low) and (Average-Tip is Low) and (Generous-Tip is Medium) (1) 5. If (Food-Quality is Good) and (Service is Bad), then (Cheap-Tip is Low) and (Average-Tip is Medium) and (Generous-Tip is High) (1) 6. If (Food-Quality is extremely Good) and (Service is Bad), then (Cheap-Tip is Low) and (Average-Tip is Medium) and (Generous-Tip is very High) (1) 7. If (Food-Quality is Bad) and (Service is Good), then (Cheap-Tip is Low) and (Average-Tip is Medium) and (Generous-Tip is High) (1) 8. If (Food-Quality is Good) and (Service is Good), then (Cheap-Tip is Medium) and (Average-Tip is Medium) and (Generous-Tip is very High) (1) 9. If (Food-Quality is very Bad) and (Service is very Good), then (Cheap-Tip is Low) and (Average-Tip is Medium) and (Generous-Tip is High) (1) 10. If (Food-Quality is very very Good) and (Service is very very Good), then (Cheap-Tip is High) and (Average-Tip is very High) and (Generous-Tip is extremely High) (1)
The following code
fis = readfis ('sugeno_tip_calculator.fis');
puts ("Output of: showrule(fis, [2 4], 'symbolic')\n");
showrule (fis, [2 4], 'symbolic')
puts ("\n");
Produces the following output
Output of: showrule(fis, [2 4], 'symbolic') 2. (Food-Quality == Good) && (Service == Bad^3.0) => (Cheap-Tip == Low) && (Average-Tip == Low) && (Generous-Tip == Medium) (1) 4. (Food-Quality == Bad) && (Service == Bad) => (Cheap-Tip == Low) && (Average-Tip == Low) && (Generous-Tip == Medium) (1)
The following code
fis = readfis ('sugeno_tip_calculator.fis');
puts ("Output of: showrule(fis, 1:4, 'indexed')\n");
showrule (fis, 1:4, 'indexed')
puts ("\n");
Produces the following output
Output of: showrule(fis, 1:4, 'indexed') 1.30 1.30, 1.30 1.20 1 (1) : 1 2 1.30, 1 1 2 (1) : 1 2.20 1.20, 1 2 3 (1) : 1 1 1, 1 1 2 (1) : 1
The following code
fis = readfis ('sugeno_tip_calculator.fis');
puts ("Output of: showrule(fis, 1, 'verbose', 'francais')\n");
showrule (fis, 1, 'verbose', 'francais')
puts ("\n");
Produces the following output
Output of: showrule(fis, 1, 'verbose', 'francais') 1. Si (Food-Quality est extremement Bad) et (Service est extremement Bad), alors (Cheap-Tip est extremement Low) et (Average-Tip est tres Low) et (Generous-Tip est Low) (1)
