Abstract
This note presents a consistent approach to evaluating the reduction of an array along an empty axis, giving results which agree with accepted values where these exist and also giving unique and consistent results for the Nand and Nor functions.Note: For clarity, the body of this paper deals only with vectors; the extension to higher-rank arrays is straightforward.

Measurement Method for Orthogonal Three Intersecting Axis Perpendicularity of Three-Axis Turntable
ISDEA '13: Proceedings of the 2013 Fourth International Conference on Intelligent Systems Design and Engineering ApplicationsThe perpendicularity of three-axis turntable directly affect the turntable's work precision, and orthogonal perpendicularity error of the three-axis turntable is mainly controlled by measuring length, dial gauge, precision and azimuth axis deviation ...
Axis control in SAC
IFL'02: Proceedings of the 14th international conference on Implementation of functional languagesHigh-level array processing is characterized by the composition of generic operations, which treat all array elements in a uniform way. This paper proposes a mechanism that allows programmers to direct effects of such array operations to non-scalar ...
