EXPLICIT FORMULAE FOR COMPUTING ASTM INTL. WEIGHTING TABLES OF TABLE 5

摘要

In this paper, a matrix and vector presentation is used for computing the ASTM International weighting tables of Table 5 for calculating the CIE tristimulus values. The method given in this paper is simpler and easier to understand and programming, especially for using MATLAB for computations, compared with the method given by ASTM International E2022. Besides, comparisons between the ASTM Intl. Table 5, direct selection, the optimum, and least squares weighting tables are given.
