Specifies that a series of transact - sql statements , which together do not produce a side effect such as modifying a table , define the value of the function 指定一系列定义函数值的transact - sql语句，这些语句在一起使用不会产生负面影响（例如修改表） 。
The basic idea is to find iterative points which converge to optimal point and its corresponding objective function or merit function values converge to optimal value 其基本思想是构造迭代点来逐步逼近最优点，相应的目标函数值或评价函数值逼近最优值。
Feedforward networks use back propagation algorithm to train a multi - layer network . after training , the multi - layer network can fit the function in the data space very well 前向网络利用反向传播算法训练多层网络，使训练后的网络较好地拟合样本空间中各点的函数值。
At last , this paper uses the rbf neural network that was optimized by the mentioned parallel model to predict the value of some nonlinear functions and the close of several stocks 最后，本文应用上述并行模型优化的rbf神经网络对非线性函数值以及证券个股收盘价进行预测。
First , we develop the local search such that the search direction , search radius and numbei of search points are adjusted according to the previous search result 首先改进了局部搜索算法，使得搜索方向，搜索半径和搜索所计算的函数值个数根据已有的搜索结果而自适应调整。
( 3 ) usevpq . dll : common statistical distribution library provides methods of getting the expectation , variance ^ probability and quantile of 10 kind of statistical distribution Dll ：常用数理统计分布的工具库提供了计算十种常用统计分布的期望、方差、函数值、分位点的方法。
Radial basis function network constructs many basis functions , according to the distances between the unknown style and the known styles , to generate the function value of the unknown style 径向基函数网络利用未知样本与已知样本间的距离构建多个基函数得出未知样本处的函数值。
Applying the method of subordinate function , nine physiological drought resistance indexes of 3 species were measured and a comprehensive evaluation on drought resistance of them was given 摘要对红柳、侧柏、合头草的9个抗旱指标进行了测定，并运用隶属函数值法对三种树种抗旱性进行综合分析。
If there exists a constant ， such that for any given positive number , there is a positive number ， such that if ， then . then the constant is called the limit of as approaches 如果存在常数，对于任意给定的正数,总存在正数,使得当满足不等式时，对应的函数值都满足不等式,那么常数就叫做函数当时的极限。
In order to reduce the value difference on the level of number of sub - objective function , the objective function is processed by first transforming the sub - objective functions and then resorting to the method of weigh - adding 为了消除各个分目标函数值在数量级上的较大差异采用先转化后加权的方法处理目标函数。
