SAX: Difference between revisions

Revision as of 18:42, 27 April 2022

SAX (SHARP APL for UNIX) was a version of SHARP APL offered by Soliton Associates. Notable features of SAX include function rank, the Rank operator, and leading axis theory, as well as relative comparison tolerance and close composition operators including Under.

All scalar functions have rank zero.
