vector(size_type n, const T& value) { fill_initialize(n, value); }当我们以 push_back() 将新元素安插于 vector 尾端,该函式首先检查是否还有备用空间?如果有就直接在备用空间上建构元素,并调整迭代器 finish,使 vector 变大。如果没有备用空间了,就扩充空间(重新分配、搬移数据、释放原空间)。
'autodetect'(default) — The dependency analysis process detects and includes the required support packages automatically. 'none'— No support packages are included. Using this option can cause runtime errors. A string scalar, character vector, or cell array of character vectors — Only the specif...
15. After move operation, do not assume any state of the moved obj. e.g. People may assume a moved vector has size() as 0 and the call of empty() on it return true. But it is not necessarily the case: perhaps the underlying whole pimpl object was moved away, the call of empty...
