ar­rayjob – Ar­ray data struc­tures for (La)TeX

This pack­age pro­vides ar­ray data struc­tures in (La)TeX, in the mean­ing of the clas­si­cal pro­ce­du­ral pro­gram­ming lan­guages like For­tran, Ada or C, and macros to ma­nip­u­late them. Ar­rays can be mono or bi-di­men­sional. This is use­ful for ap­pli­ca­tions which re­quire high level pro­gram­ming tech­niques, like al­go­rith­mic graph­ics pro­grammed in the TeX lan­guage.
The pack­age is now su­per­seded by the ar­rayjobx pack­age, which has the same spec­i­fi­ca­tion but is less er­ror-prone.
