摘要
以《大测》中"三要法"和"二简法"为计算公式,利用"六宗率"作为初始计算条件,利用计算机程序语言对《大测》中的造表步骤进行程序化,并从算法角度对其进行复杂度分析,得到复杂度分别为:8 570次和6 570次。构造程序所得函数值与《割圆八线表》中数值多处不符,从而验证后者数值并非来源于《大测》造表法。
The procedure of building trigonometrice table which used formulas of Sanyaofa and Er- jianfa in Dace,with the initial calculate condition for Liuzonglv, is programmed by computer words.Af- ter analyzing the complexity of calculate, we got two complexity both are 8570 and 6570 times. The procedure is incomformity with Geyuanbaxian Table,thus we can confirm the number isn' t from Dace.
