By studying the functional properties of index expressions of array elements in FORTRAN DO-loops, a new algorithm, called the associative function algorithm, is developed. In this algorithm, when the index expression of an array element in a loop is a linear function of the controlled variable of that loop, a sufficient-necessary condition for vectorization is given,otherwise a sufficient condition is given. The algorithm puts fewer strains on the index expressions of array elements...

By studying the functional properties of index expressions of array elements in FORTRAN DO-loops, a new algorithm, called the associative function algorithm, is developed. In this algorithm, when the index expression of an array element in a loop is a linear function of the controlled variable of that loop, a sufficient-necessary condition for vectorization is given,otherwise a sufficient condition is given. The algorithm puts fewer strains on the index expressions of array elements and is easy to realize.

本文通过对FORTRAN DO循环中数组元素下标式的函数性态的分析研究,给出了一种新的向量化算法——这种算法作者称为“相关函数法”。FORTRAN DO循环向量化的相关函数法,对于循环中数组元素的下标式是循环控制变量的非线性函数时,给出了向量化的充分性准则;对于数组元素的下标式是循环控制变量的线性函数时,则给出了向量化的充分必要条件,本算法的特点是:由于对数组元素的下标式限制少,并且算法简便,所以适应面广,易于在机器上实现。

A sufficient necessary condition for the linear nonhomgeneous periodic system to have unique ω periodic solution is given. Apllying this conclusion to the ordinary coefficient linear nonhomgenous periodic system we can get a simplier method to judge whether it has unique ω periodic solution.

本文给出了线性非齐次周期系统存在唯一ω周期解的充要条件,并将其应用于常系数线性非齐次周期系统,得到它存在唯一ω周期解的一个比较简单的判别法。
