With the development of Internet technology, the era of vector images of Android has come. In Google's newest support library v23.2, the AppCompat class has already used vector images, which reduces the AAR package by 9%, about 70KB, to all the newer applications. Of course, we can also use vector, slimming application. Vector images are the manifestation of the SVG format in Android. SVG image adaptation screen, the picture is small, there are many advantages, reference. The analysis of

Reference Blog: http://blog.csdn.net/u011092188/article/details/77430988 The representations of the various forms in the Eigen library are as follows:1: Rotation matrix (3x3): eigen::matrix3d--uses a matrix to represent the rotation transformation relationships in space2: Rotation vector (3X1): eigen::angleaxisd--with a rotating axis and a rotation angle to represent rotation3: Four Yuan (4X1): eigen::quaterniond--with 4 variables to represent rotation, can avoid universal joint lock phenomenon4

1 why the interrupt vector table should be remapped. COREM3 authoritative guide "However, for dynamic redistribution interrupts, CM3 allows vector table relocation- -Start locating the exception vectors from other addresses. the area corresponding to these addresses can be a code area, but it can also be a RAM area. The entry address of the vector can be modified in the Ram area. ”。 Puzzle: 1. If you do not remap, the address of the interrup

This article is from a practical program I picked out, so there is not much narrative stuffFirst of all, sort needs a header file.#include This sort is primarily for a custom vector typeSuch as:typedef struct ad{int len; string name;} AdVectorFor the adtemp sort, the first need to set the collation of their own, of course, or according to the type of int variable is a good sort, because it is a custom structure so convenient and practical for the key haOK sorting rulesThis is sorted in ascending

Write a program that reads two strings, compares them for equality, and outputs the results. If not equal, the output of the larger string.

1. Define an array without having to specify its memory size, such as int n[]={1,2,3,4,5}, which is an array of space 5.The use of 2.const, const must be initialized, otherwise it will error, and after initialization, can not be changed.3. The difference between a static local array and an automatic local array: In fact, a static local array is mainly an analysis, using static, such as static int arr[5], the main difference is if we use a static local array, once modified or initialized, is vali

Http://codeforces.com/problemset/problem/598/CThe main idea is to give you the starting point of a vector vector is the minimum output of the 0,0 from the beginning of the (*) vectorThis is the first contact with the polar angle.The distance from a point to the origin of a function image is the polar diameter, and the angle between the polar diameter and the x-axis is the polar angle.Sorting by polar angle is from the rightmost beginning of the third quadrant to the far right of the second quadr

With the result, we can see that the data is cleared after clear (), but capacity () is still 4.Suppose: we create a new vector from the original vector, so let's see what happens.View CodeResults:V.capacity () 4v1.capacity () 3As can be seen, V1 's capacity () is the actual size of V, so it can achieve the purpose of

I. at () and operator[]void f(vectorThere are two ways to randomly access the elements in a vector operator[] and at (), the difference between the two methods is mainly The at () function checks for bounds and throws an exception for out-of-bounds Std::out_of_range Operator[] does not perform bounds checking, and if it is out of bounds it can directly cause a program crash As a result of the above differences, at () each time the boundary check, so that the speed i

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 memory related to storage elements. We call vector a container because it can contain other objects. All objects in a container must be of the same type. Before using vector, the

Push_back is to insert an element at the end of the vector,The erase () function in the vector removes the element at the specified position from the specified container or an element within a range, and after deletion, the return value is also an iterator pointing to the next element of the last deleted element.The problem is that the iterator becomes a wild pointer and needs to re-point the iterator pointer to begin or assign the returned iterator to the original iterator, or it will report a
