定义了一个vector容器，元素类型为vector<int>，初始化为包含m个vector<int>对象，每个对象都是一个新创立的vector<int>对象的拷贝，而这个新创立的vector<int>对象被初始化为包含n个0。每部分解析：构造函数vector(size_typen, const allocator_type& alloc = allocator_type())表示构造一个使用alloc...
1、vector<int> a(5); //定义了5个整型元素的向量（<>中为元素类型名，它可以是任何合法的数据类型），但没有给出初值，其值是不确定的。2、vector<int> a(5,1); //定义了5个整型元素的向量,且给出每个元素的初值为1 3、vector<int> a(b); //用b向量来创建a向量，整体复制性赋值 4...
φ(t)=12πeit=12π(cost+isint). None of the functions ϕn just defined lies in the space L2(−∞,∞) because the waves do not “die out” as ∣t∣→ ∞. Special bases for L2(−∞,∞) that have particularly attractive decay properties, called wavelet bases, have been studied...

qinterpf Interpolate between quaternions, given a fraction from one to the other. qinv Invert a rotation quaternion (quaternion conjugate). qpos Return the equivalent quaternions with positive scalar part. qrot Rotate the frame for a vector using a quaternion. ...
Once the integrity of the received message is verified and the message is decrypted using the security keys (KNAS int and KNAS enc), the NAS security setup is completed [18,20]. When the NAS security setup is finished, AS security setup procedure between UE and eNB begins. However, since...
