指示函数(Indicator function): 如果C为凸,那么其指示函数为:\({I_C}(x) = \left\{ \begin{array}{l}0,x \in C\\\infty ,x \notin C\end{array} \right.\)为凸函数。 最大值函数(Max function): \(f(x) = max({x_1}, \ldots ,{x_n})\)为凸函数 凸函数的特性 上镜特性(Epigraph ...
The object uses the storage class GetSet. The GetFunction and SetFunction properties are set to the defaults, get_$N and set_$N. The generated code uses the function names that you specify in GetFunction and SetFunction to read from and write to the data. The code replaces the token ...
下面的代码创建了一个类,每次访问get或者set都会打印一条信息.重载__getattribute__()也可以使每个属性实现这一方法,然而,描述符在查看特定的属性时比较有用 class RevealAccess(object): """A data descriptor that sets and returns values normally and prints a message logging their access. ...
A set is also described as a class template because the functionality it provides is generic and independent of the specific type of data contained as elements. The data type to be used is, instead, specified as a parameter in the class template along with the comparison function and ...
Slicing. As explained in Limiting QuerySets, a QuerySet can be sliced, using Python’s array-slicing syntax. Slicing an unevaluated QuerySet usually returns another unevaluated QuerySet, but Django will execute the database query if you use the “step” parameter of slice syntax, and will ret...
The aim of the guidelines is to help people to use modern C++ effectively. By "modern C++" we mean C++11 and newer. In other words, what would you like your code to look like in 5 years' time, given that you can start now? In 10 years' time?
Specifically, for all values X and Y of type Key, the call key_eq()(X, Y) returns true only if the two argument values have equivalent ordering; the call hash_function()(keyval) yields a distribution of values of type size_t. Unlike class template unordered_multiset Class, an object ...
