It is also possible to define functions with a variable number of arguments . there are three forms , which can be combined 有时需要定义参数个数可变的函数。有三个方法可以达到目的,我们可以组合使用它们。
The corresponding user - defined function is called , with an argument list that is one longer than the argument list of the call : the instance becomes the first argument 调用对应的用户自定义函数,其参数个数比普通的函数调用多一:该实例成为方法的第一个参数。
Model combining should comply with the data - coherence rule , such as the type of data , the number of parameters , etc . the process of model combining should be convenient and transparent for users , which means the users do n ' t n need caring the coherence of data 模型间的组合不是随意的,必须满足数据一致性要求,包括数据类型和参数个数的一致等。模型组合的过程对用户应尽可能简便、透明,用户毋须关心模型间的数据一致性问题,但系统必须实时进行数据一致性检查。
The quad method can detect n - m - 1 gross errors in theory , if there exist , ( n is the number of observations , m is the number of unknown parameters ) and its breakdown point is much high , so its application prospect is very broad in many fields . the quad method program is preliminarily designed with matlab language for its powerful matrix function , simple language and friendly interface 拟准检定法是一种高崩溃污染率的数据检测方法,理论上,能探测到n - m - 1个粗差(如果存在粗差) ( n为观测个数, m为待估参数个数) ,因此该方法在许多领域有比较广阔的应用前景。
Orthogonal matrixes have special structures , and every row vector of them can be taken as a plot , which may be parametrized in n - sphere space . through the research of structures of orthogonal matrixes , the writer finds a parametrized matrix , which can express all the orthogonal matrixes . through analysing uprightness between related high - order planes and the number of required parameters , we get the maturity of this method 自然的,这些点可以用其球坐标,即与各坐标轴的夹角来参数化,作者通过观察正交矩阵的几何结构,最终找到了任意维数的随机正交矩阵的参数表示方法,通过分析相关超平面之间的垂直关系和参数化正交矩阵需要的参数个数,论证了这种表示的完备性。
Using a parameter name is generally a much better programming practice than referencing parameters by index value , because it reduces the need for maintenance if the number of parameters changes and frees you from having to remember whether a stored procedure returns a value . oledbdataadapter1 . selectcommand . parameters [ " title _ keyword " ] . value = titlekeyword ;编程时使用参数名通常比通过索引值引用参数好得多,因为它减少了在参数个数变化时的维护需要,并使您不必记忆存储过程是否返回值。
Phases based on organizational structure and program characteristic of user lib - function . firstly , we can translate the middle - code of user lib - function into the middle - language program that , can - be de - compiled , after . , that , resume corresponding functions name , parameters number , parameters type by - existing methods and technologies 通过潜心研究发现,可以根据用户库函数的组织结构和代码特征,将识别过程分为两个阶段,首先将库函数中间代码翻译为可以逆编译的中间语言程序,然后通过现有方法和技术恢复出相应的库函数名、参数个数及类型等。
Then , the effects of the inner force and displacements of the exterior - protected structures influenced by the value of m and the different depths of inner poling are analysed with the m - method back - analysis programme . and the variation of optimized values caused by the numbers of different inversion parameters is also analysed , and a conclusion is drawn that a propriate parameter numbers should be in use of back analysis 然后,利用编制的m法反演分析程序,分析了m值对围护结构内力和位移的影响,计算了内支撑不同设置深度对围护结构内力和位移的影响,分析了反演参数个数对反演优化值的影响,即对解的适定性问题进行了讨论。
