This article is only intended to show the effects of several Fedora15 files on BNS. I was thinking about adding this article to the previous article about Fedora15 installation and configuration. However, this article is long and difficult to edit, so I just want to open another article. Again, Fedora15 has a very good performance on MBP. We recommend that you try it out.

Vectors are vector types that can hold many types of data, such as several integers, so they are called containers. Vector is an important member of the C + + STL, and you need to include the header file when you use it:
Copy Code code as follows:
#include
Vector initialization: There are five ways to do this, examples are as follows:
(1)
Linear correlation of the first section vector group
A Mathematical Concepts
Defines 1.1 n ordered numbers, the array of which is called an n-dimensional vector, which is called n components of the vector, and the number I is called the first component.
Definition 1. 2 to the directional measure group A:, for any set of real numbers, vectors
A linear combination
Summary of several situations of vector vectors in c ++ (vector pointer and pointer vector)
1. Standard Library vector type
Vector is a set of objects of the same type. Each object has a corresponding integer index value. The standard library will be responsible for managing
In three-dimensional space, the product of two vectors (a vector product, an outer product, a product, a multiplication of multiples of two vectors: the inner product, the dot product) represents the torque of two vectors, and the mixed product axb of three vectors C, the area of the parallelepiped that is composed of three vector a,b,c. And the position of a,b,c in the mixed product is interchangeable (thi
In practice, the vector series in c ++ -- creating vector of local structure AND vector of structs initialization
I have never used it beforeVector
Now, write a short code:
#include
#include
int main() { struct st { int a; }; std::vector
v; v.resize(4); for (std::
I've never used it before.vector#include #include intMain () {structSt {intA };STD:: vectorV V.resize (4); for(STD:: vector:: Size_type i =0; I operator[] (i). A = i +1;//v[i].a = i+1;} for(inti =0; I STD::coutSTD:: Endl; }}Compile successfully with VS2015, run result:1234However, this is only allowed after c++11, the compiler does not allow you to write such a syntax, the vector container is not allowed to
C ++ copies the content in a vector to the end of another vector and ends with the vector.
When using the vector container, We need to copy the content of a vector to the end of another vector. How can this problem be achieved?
See C++primer Plus look bored, the first time do Leetcode practice, originally want to do two-dimensional vector, results always pass, check the reason, must use one-dimensional ...One-dimensional answers:Class Solution {PublicVector{int cout = Nums.size (); Get the size of the vectorvectorfor (int i = 0; i{for (int j = i + 1; j{if ((Nums[i] + nums[j]) = = target){Ret.push_back (i); Get the location of the target valueRet.push_back (j);}}}return ret;}
In practice, the vector series in c ++ -- vector (unique_ptr () is assigned to vector (unique_ptr ())
Previously, we mentioned that the insert method can be used to copy a vector to the end of another vector.
As mentioned in previous blogs, if unique_ptr is placed inside the
In practice, the vector series in c ++ -- vector traversal (stl algorithm, vector iterator (do not judge not equal to end () in the loop), operator [])
There are many ways to traverse a vector container.
Index traversal:
for (i = 0; i
Iterator traversal:
for (vInt::const_iterator iter = v.begin(); iter != v.end();it
Previous blogs about vectors you can use the Insert method to copy a vector to the back of another vector.Previous blogs have also talked about the need to transfer ownership if the vector container is placed inside the unique_ptr.Come on, now. 818 HowvectorIf you have a regular vector, we can use insert like this://inserting into a
Vector series in practice c ++-sort the vector using the sort algorithm (sort the vector (string) and use stable sorting std: stable_sort ())
After writing a lot of vector operations, we encountered the Sorting Problem of the vector in our work. Here we will discuss it.
Use
It is well known that SVM is a global optimal solution by solving a two-time programming problem, which leads to a lot of memory and time in practical applications. Most of the existing methods reduce support vectors by reducing training samples, which speeds up training. This article is from Li Qing and other paper "Support vector machine pre-selection based on vector projection".
The basic idea is that M

In the Gaussian mixture model, I mentioned the general process of feature processing:
In fact, the Gaussian mixture model completes the task of K-means, then through the Gaussian mixture model clustering, also uses the general distance based method to carry On feature encoding. No, the Gaussian mixture model is usually used in conjunction with Fisher Vector. Now let's make a brief introduction to Fisher Vector
