| 摘 要： | 本文提出的割线抛物线法(简称割抛法)是求一元函效凸点的一种算法。它可以配合函数插值拟合方法直接进行精确的一维搜索,而无需确定搜索区间(当然,也可以用它确定搜索区间)。求凸点的割抛法使一维搜索的效率明显提高。

| Abstract: | The secant-parabola method(SPM)advanced in this paperis an algorithm to find convex points of monadic function. It may be usedto make accurate unidimensional searchs directly with the function-fittingmethod and does not need to determine the search interval(it may be usedto do, if require, of course). The method makes the efficiency raise obviously. |
